Your assignment today is to watch this (I think) interesting video. I hope you find it interesting as well. Thanks :)

think of all the development throughout history of the Comedian says you enjoy today cuz I have to pick the biggest Game Changer in human technology it would probably be steam engine during the Industrial Revolution machines and farms and factories involved in no time and I noticed small people in about hundred years and three main event has it took to make this wall changing technology Jeep engines like steam engines have several energy into mechanical work and they do it in a repeating cycle 48th and Enzo operating temperature t l c well at the school and the engine temperature is I can stop the cycle again set the temperature to stop the phone to the engines in put heat must be equal to 18 type the engine keeps blacking out the inside the inside she is used to C7 intake valve opens outward stops about somebody can an intake valve poses an exhaust valve open the exhaust valve lead to a condensed that makes the Piston move back into its original position back into steam and the cycle stopped kind of different movements that the steam engine runs it releases the engine is an engine engine is how to calculate its efficient like I said earlier and engines in seconds is equal to the rocket does + 10 / 7 times of impact heat and exhaust heat pretty easily and efficiently is equal to 1 - 6 these are the important tools we say that its efficiency was exactly one it would be perfectly efficient is there such thing as an engine that produces no exhaust heat a towel and then raised again for the engines TECO energy is he with his nose fiction or anything like that we need to run it back to transfer heat from something with a low temperature something with the highest temperature it's kind of hypothetical engine is a Carnot engine and we can use it to figure out the maximum possible efficiency of a real-life engine the condo engine combines to as I type what's known as the Kane cycle but in the, a cycle that I hate between areas with different temperatures because it's an engine from an area with a higher temperature to an area with a then reversing the engine would involve cats are in heat formula but the Hyatt violate the second law of Thermodynamics to isothermal process is way heat is transferred the temperature is held constant so the heat never flowed between areas of different temperatures you might be wondering how he has no difference in temperature in those cases that are very tiny given temperature and there immediately eliminated so practically speaking that is no transfer of heat between areas of different temperatures and this means the price of can still be reversed and wax at least in theory because again, when did the second crisis is adiabatic how to draw for the Heats a constant volume expands and the pressure decrease stop puffy C on the diagram for the temperature is held constant as pressure increases while it's volume decreases the second is adiabatic volume decrease and it's pressure increase like FBA the temperature goes back up to the starting point the condo engine is the ideal engine because it produces the most possible from a given temperature difference because the condo engine is the high temperature that proportional to the end an exhaust fix it means that in the equation for efficiency with t h and T L engine Symphony gooski's but you do know it's off baking temperatures the identification key for an engine is equal to 1 - it's low temperatures / high temperature temperature is an engine to power a life-size Mario top your building if I did engine I'm not thinking about buying it but it's exhaust he is to kid shows at 300 efficiency is equal to 1 / 0.8 that would be a very efficient engines he should be a little bit suspicious I mean that kind of efficiency even possible you can find out why in the ideal efficiency of the engine the Connor efficiency is equal to 1 - temperature / Pi operating temperature which in this case is it impossible for this engine to have an efficiency higher than the manufacturer's website is we'll just lying they probably shouldn't buy anything from them anyway he probably wouldn't want an engine of the price of the efficiency of a Carnot engine what could cause no engines very slow mo prices it has to be kept constant while he is transferred which only was at the heated Chance by the super slowly so the engine has to be really slow if you had a condo engine in your car for example it would take you a whole face get out your driveway and into useful could I use the photo of heat from something warm up to something cooler to produce what what if you want to keep the flow from something cooler something warm up refrigerated land from creating steam engine steam cleaning machine I'm not like the opposite of heat engines in the sense that they used in the opposite direction as it evaporates in the fridge uses the most astute gas outside of the refrigerator when it releases the Specialties measured by the web for Jeeps given amount of insight what is a similar concept to refrigerate is the coefficient of performance will CRP which is equal to the amount of heat removed from the lower temperature Zion / the was the higher the coefficient of performance if we could rewrite the CIP equation Justin's house of que ell and qh the coefficient of performance is equal to 2 L / qh SQL dealer for Theresa we do the same thing we did with the ID Connor engine replace ql with TL and qh with THC for an ideal fridge the coefficient of performance to be equal to the low operation temperature / the higher operating temperature minus the law writing temperature caught have a high coefficient of performance the steam engines and refrigerated opposites only made possible by Han Nolan you mentioned about how engines has double and I can have a calculator efficiencies we will they describe the Connor engine and finally he talks about cutting machines like in association with PBS digital Studios how do I get to bed, one check out that I listen to latest episodes from shows like PBS space-time be plucked since I'm home black people equally amazing graphics Apple Cafe
