Keep in mind that these tasks extend upon those in the “Investigate” section and are designed for older or more advanced students. Use the “Investigate more” section of the student project as an optional extension. Investigate more (optional, 45-60 minutes) Have your students collect their answers with text or pictures in the Documentation tool. Sometimes flexible structures or materials are more resistant than stiff and strong ones. Does “resistant” mean the same thing as “strong”?.How are modern buildings designed to withstand earthquakes?Īrchitects and engineers use structures, principles, and simulations to test.Structural designs and various materials are other important factors to consider when testing building resistance.

Until now, heat pump water heaters have only been available with 240 volt electrical connections. The newest development in heat pump water heating is the production of a 120 volt 15 amp version. Both use 240 volts of electricity so making the transition is relatively easy.īut what about the other 54% of water heaters across the nation, the 64 million, mostly natural gas powered, machines that are heating the nation’s water? The lowest hanging fruit to more efficient water heating is to replace every inefficient, electric resistance water heater with a hybrid electric heat pump water heater. Heat pump water heaters are orders of magnitude more efficient than polluting natural gas and old electric resistance water heaters, which means families will save hundreds of dollars a year in energy costs and literal tons of CO2 emissions.ġ20 Volt Versions Make Gas Switch-Outs Easier I’ve already written a full CleanTechnica article on the topic in which I called them game changing machines (this happened to be my best read CT article ever and editor, Zach Shahan, laughed that an article on water heaters was the top read for the week). They clean up the way we heat our water and reduce, and potentially eliminate, CO2 emissions from water heating. Heat pump water heaters are a rare example of a silver technological bullet. Heat Pump Water Heaters Are Game-Changing With the right water heater we can have our cake and eat it too: we can have all the hot water we need and save money and not pollute. Water heaters are the second biggest energy user in a typical household in the US, and a clean version of this boring technology might help save the day and our planet. Until relatively recently, no one thought much about the big tube-like machines with pipes and wires sticking out of them that sit in our closets, basements or garages, and somehow provide all the steamy showers we could ever want.īut how we heat water matters greatly in our efforts to decarbonize. In previous, pre-climate catastrophe times, news about a new type of water heater might be laughable. This opens up the world of efficient water heating to many more households because they won’t have to rewire their homes to make the switch. 120 volt 15 amp heat pump water heaters are set to hit the market (most early next year) allowing homeowners with gas water heaters to easily switch them out for heat pump water heaters without expensive electrical panel upgrades. There are big developments happening in the world of water heating. This water heater is expected to hit the market in the first half of 2022. AOC varies by gallon capacity.Updated: Editor’s note – a previous version of this article stated that the Rheem 120 V water heater was already for sale. 10Based on AOC comparison of 40, 50, 65 and 80 gallon Ruud Ultra Heat Pump with HydroBoost water heaters and standard gas water heaters of similar capacity. 9Based on comparison of 40, 50, 65, and 80-gallon Plug-in heat pumps and standard gas tanks of similar capacity with minimum efficiency. 8As compared to standard integrated heat pump water heaters. 7Based on AOC comparison of 40, 50 gallon Ruud Ultra Heat Pump water heaters and standard gas water heaters of like capacity. 6WiFi broadband connection and Ruud Contractor App required connection between water heater and app dependent on external factors beyond Richmond’s control.

Is using some of the results of the last few videos and a So from the center to theĬircumference at any point, this distance, the Then this is side length a, and that is also a That means all of these sides are the same length. So I'm going to try my best toĭraw an equilateral triangle. This triangle sit on the circumference of the circle. So let's say this is a circle,Īnd I have an inscribed equilateral triangle Is use some of the results from the last several videos toĭo some pretty neat things. So when you take off the circle the area is 144 * SQRT(3) - 48 pi Using Heron's formula the area is 24^2 * SQRT(3)/4ġ7. So the area of the circle is 48 pi you need to find the area of the equilateral triangle.ġ5. The area of the circle is (4 * SQRT(3)^2 * pi which is also 48 piġ4. If you rationalize the fraction you get r = 12 * SQRT(3) / 3ġ3. Half the base of the equilateral triangle is 12. If you drew the 30-60-90 triangle on the base of the equilateral triangle you can see the longer leg of the 30-60-90 triangle is the same as half the base of the equilateral triangle. This cuts the equilateral triangle in half.ĩ. Now draw the height of the equilateral triangle. So you know the longer leg is r * SQRT(3)Ĩ. The radii you drew is the short side of the triangle you created.ħ. This a 30 - 60 - 90 triangle because you bisected one of the original angles of the equilateral triangleĦ. (For simplicity draw the line segments to the base, so connect the radii you are drawing to the base of the triangle where it is being touched by the circumference of the circle)ĥ. Connect another line segment to an apex of the same side. Connect a radii to any part of the circumference of the circle that is touching the triangle.ģ. Draw the figure and label the sides of the equilateral triangle in this case 24.Ģ. You can now use the formulas shown in the video for the area of the triangle and the circle.Īrea = (SQRT(3)*x^2) / 4 - pi * R^2. Just like the example in the video, the distance from the center to the outside triangle apex is 2*R, and the distance of the distance of the base of the inside triangle is SQRT(3) R, and by definition that distance is x/2 (half the length of the outside triangle edge). You know this because the equilateral triangle angle was 60 degrees, and you just bisected it. This forms a right angle with that line, and that length = R (radius).Īlso draw a line from the center to a nearby apex of the triangle (on the same triangle line edge). This is a bit more challenging to do without video, but if you understood the video, you could probably follow:ĭraw the figure (outside equilateral triangle with inscribed circle).ĭraw a line from the center of the circle to a point where the circle barely touches the triangle. Let's take the example that you know the radius of the (inside) circle. or the radius of the (inside) circle, you can figure out the other. For example, if you know either the length of the (outside) equilateral triangle. The primal Sun is moving through Leo and your busy 3rd House of local communities and friendships, so it’s more than.

We are one of the most reliable companies in this domain offering PET Preform Mould with advanced mould design technology. Husky, Netstal PET line, PET Master, General PET injection molding machine When the mold temperature is low and even, the cooling speed shall be too fast with few crystallization and transparent products.72 cavity preform mould for 30/25 Neck 15.5g PreformĢ8 sec with general PET screw type of injection molding machineĬycle time with two stage injection system and Post cooling systemīalanced Hot runner with valve gate system (2) If we don’t control the mold temperature or the metal temperature properly, it’s easy to produce “white fog” and become opaque. Otherwise, it’s easy to form “bridging” at discharging chute which will influence the plasticizing. (1) Recycled material cannot be too much. If the machine stops less than 15 minutes, we only need to make air injection If the machine stops more than 15 minutes, we should not start the machine again until we use viscosity PE to clean the machine and make the feed cylinder’s temperature drop to PE temperature. Try to avoid the temperature above 300 Celsius degree. It should avoid overlong detention time to prevent from the molecular weight declining. In order to avoid wearing, the packing pressure shall be as low as possible. The material injection is usually completed in 4 seconds. But if injecting too fast, the shear rate would be so high that the material would become fragile easily. Generally, injection speed must be fast, in order to prevent premature solidification. The temperature is ranging from 270 Celsius degree to 295 Celsius degree and the enhanced GF – PET’s temperature can be set from 290 Celsius degree to 315 Celsius degree, etc. It can be measured by the air injection method. There is enough exhausting effect for it so as not to appear local overheating or chipping, but the vent’s depth is generally not more than 0.03 mm, otherwise, it is easy to produce flashing. Insulation board’s thickness is about 12 mm, and can bear high pressure. It is better to have an insulation board between mold and injection molding machine template. We generally use hot runner mold to design PET bottle preform. PET can only be stable for a short time after the melting point, and the melting point is so high, which needs to choose the injection system which has more temperature-control periods and less friction heat when plasticizing, and the product’s (the material which contains water) actual weight cannot be less than two-thirds of the amount of machine injection. The proportion of recycled material is generally not more than 25%, and the recycled material needs to be completely dried. We can use air injection method to examine whether the material is completely dry or not. Therefore, we need to dry the material at 150 Celsius degree for more than 4 hours and 3 to 4 hours at 170 Celsius degree before processing. When the water content exceeds the limit, the molecular weight of the PET will drop during the processing, so the product will be colored and become crisp. The aggregate is very sensitive to water when it’s at a high temperature. Plastic dryingĭue to PET macromolecule contains an aliphatic base, it has certain hydrophilicity. Therefore, we change the rheological property mainly from the pressure. PET has a good rheological property in molten condition and pressure has more effects on viscosity than temperature does. PET injection molding parts are mostly used in the bottle preform products At present, GF-PET is used by most clients. The chemical name of PET is poly terephthalic acid alcohol ester, also called polyester.

At the same time, parts of the country were occupied by Syria from 1976-2005 and by Israel from 1985-2000. Lebanon endured a civil war from 1975-1990. Lebanon was part of the Roman Empire in the time of Christ and was later ruled first by the Ottoman Empire (until the end of World War I) and then by France until the end of World War II. Lebanon was the home of the Phoenicians, a group of seagoing traders famous at the time for trading in Tyrean purple dye and known today for creating the earliest confirmed alphabet, which evolved into/inspired the alphabets of many European alphabets still in use today (Italian, Spanish, English, French). A mountainous country, the region that would come to be known as Lebanon has been inhabited for more than 7000 years, and its recorded history goes back to 3,000 BC. Lebanon lies on the eastern coast of the Mediterranean sea, just north of Israel, south of the Syrian Desert, and west of Syria. Easily the smallest nation in the Middle East, Bahrain squeezes 1.7 million people onto a scant 294 square miles of land, which results in a population density of about 4,690 people per square mile. In fact, Bahrain is connected to Saudi Arabia by the King Fahd Causeway, a massive series of bridges and highway that stretches 25 km (15.5 mi) across the sea, from one shore to the other. Profiles of Middle Eastern Countries BahrainĪlso known as the Kingdom of Bahrain, this diminutive country is actually a chain of small islands, 50 natural and 33 man-made, in the Persian Gulf, just off the eastern coast of Saudi Arabia. For a statistical look at the Middle East as a whole, see the table further down this page. In the next section, we will take a closer look at a few specific Middle Eastern countries. Moreover, every country in the Middle East (at least, of the 16 most often-included countries) touches a large body of water, be it the Mediterranean Sea, Red Sea, Arabian Sea, or Persian Gulf, which is helpful for commerce. Fortunately for the agricultural industry in the Middle East, numerous rivers flow, twist, and wind through the region, including the Nile, the Tigris, and the Euphrates. This is arguably unsurprising given the region's proximity to the equator. In general, the Middle Eastern climate leans towards being hot and relatively dry, especially once one moves inland from the coast. The most prominent religions practiced in the Middle East are Islam, Judaism, Christianity, Mandaeism, Baha'i, and Unitarian Druidism, along with many other smaller belief systems and practices. Arabs, Kurds, Turks, Azeris, and Persians make up the majority, and minority ethnic groups include Zazas, Assyrians, Jews, Lurs, Shabaks, Balochs, Druze, Berbers, Samaritans, Copts, and Mandeans. The countries that make up the Middle East vary greatly in size, culture, and language. In contrast, Bahrain is the Middle Eastern country with the smallest total area. The largest Middle Eastern country in terms of physical size is Saudi Arabia. List of Countries in the Middle East Always included At least one source also lists Akrotiri and Dhekelia, two tiny British territories on Cyprus, as a single separate entry. A few sources expand the area westward to include Sudan and Libya in Africa, or eastward to include central Asia ( Afghanistan, Pakistan, Kyrgyzstan, Tajikstan, Uzbekistan, and Turkmenistan). Many lists of Middle Eastern countries also include the mercurial Cyprus, which is frequently considered European politically but Asian geographically. |
