Comprehension for 41-43
The Diesel cycle is the thermodynamic cycle which approximates the pressure and volume of the combustion chamber of the Diesel engine, invented by Rudolph Diesel in 1897.The process A→B is an adiabatic compression, B→C is an isobaric expansion, C→D is an adiabatic expansion and D→A is an isochoric process
One mole of a diatomic ideal gas(γ=1.4) is taken through cyclic process starting from process A. The volume ratios are VA/VB=32 and VC/VB=2 and the temperature at A is TA=300 K
take 2-8/5=0.33
Temperature of gas at state D is
