Example: solving an ideal Otto cycle

[@Almont2]

Thank you so much These 5 minutes are better than 2 hours explaining the professor

[@arifhakiminadnan4880]

mohammed Ali bro is it constant value for k = 1.4 ( isentropic ) ?

[@Almont2]

Hakimin Ally K=CP/CV K=1.007/0.718=1.40

[@arifhakiminadnan4880]

thanks bro

[@i1945us]

love how you explained it straight to the point, others love beating around the bush! thank you!

Good presentation. This example appears to illustrate a cold air-standard Otto cycle, which assumes a constant specific heat. Modeling as an air-standard Otto cycle yields a slightly different result. The thermal efficiency (cold-air standard only) also can be calculated from eta = 1 - (T1 / T2)

Excellent video!! I literally did my homework with your video. Thanks :D

This feels like one of those classes where you're desperately trying to write down the notes, and then the teachers erases them XD Must admit, I did completely understand it

[@Aprst25]

Do you always choose the cv for air to be .718? Because on the tables it shows at 300k the cv is .718 but in this problem there's no 300k

[@workingballer]

wow thank you! plz make more videos! very clear steps

[@emjoneshouseDIY]

its amzing how hard it is to find a good example problem worked on this one was so close until totally ignores the k in the first equation. please remind me WHERE THAT COMES FROM!!!!!

[@jude3046]

Eric Jones if you have a textbook handy, check the back appendix for "Ideal gas specific heats of various common gases", and look under "air" for the k value.

[@ozkantekin90]

+Eric Jones k is specific heat constat also cp/cv givs the same result this is valid for ideal gases

[@emjoneshouseDIY]

Thank you to you both

bro u just saved my life, ty

[@paolajadecalunsag5876]

Where did 1.4 come from??? Helpp

[@masonbeltran7144]

That's the Cp/Cv for air

[@aerolfrancedeguzman9622]

1.005/0.718

[@small_ed]

Isentropic exponent (k) 1.3 for triatomic and higher molecules 1.4 for diatomic (including air)

I am Veryy Thankful. Awesome Explanation
