(adsbygoogle = window.adsbygoogle || []).push({}); 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.
