1. Please help with the following question. Given: A Heat engine goes through a Carnot Cycle as the following states: State 2 to 3: air compresses adiabatically (pressure increasing) State 3 to 4: air expanded under isobaric process State 4 to 1: air goes under adiabatic expansion process State 1 to 2: air goes under an isobaric compression Expression : efficiency = 1-(v1/v4)^gamma(v4/v3) Find: 1: Plot P-V and T-V diagram of the cycle 2: Prove that the efficiency of this cycle given by expression (1) 3: Determine the net work done by this cycle as function of pressure and volume. Thank you 2. efficiency = 1-TL/TH efficiency = 1-(v1/v4)^gamma(v4/v3) 3. I have done the graphs correctly, I am not expecting anyone to do it for me, just some guidance on the right direction to start.
