Thermodynamics- piston cylinder- 2nd law of thermodyamics
( part a only I don't understand how you know from this question that it is a constant pressure process. I thought it is a polytropic process. So it will have a pVγ curve. I was drawing a pV curve. The answer is a straight line parallel to x- axis. My question: How do I know from...- student23

What is the difference between compression ratio and cut off ratio?
Is it possible to explain it much simpler please? ( I am very weak in physics.) So basically, What I know so far is (in simple steps) 1) In a box, air is compressed. 2) Fuel is added so 3) ignites 4) and produce work if compression ratio goes up, efficiency...- student23

What is the difference between compression ratio and cut off ratio?
Why does the efficiency go up with compression ratio and the cutoff ratio down? (I don't really understand the physics/thermodynamics behind it Thank you- student23
