Given the Pv and the Ts diagrams below identify the four pro

Given the P-v and the T-s diagrams below, identify the four processes taking place in this thermodynamic cycle:

From the given P-V diagram and T-s diagram, it is clear that the

i) 1 -2 process is constant temperature process.

ii) in process 1-2, the volume at 2 is less that volume at 1. Also , the pressure at 2 is more than pressure at 1.

Thus process 1-2 is isothermal compression process.

iii) 2-3 is a constant volume process.

iv) In 2 -3 path, temperature and pressure at state 3 is more than at state 2.

Thus process 2-3 is Isochoric heat addition or constant volume heat addition process.

v) 3 -4 process is constant temperature process.

vi) in process 3-4, the volume at 4 is more than volume at 3. Also , the pressure at 4 is less than pressure at 3.

Thus process 3-4 is isothermal expansion process.

vii) 4-1 is a constant volume process.

viii) In 4 -1 path, temperature and pressure at state 1 is less than at state 4.

Thus process 4-1 is Isochoric heat rejection or constant volume heat rejection process
