3. Air in a closed vessel of fixed volume 0.25 m3 exerts pressure of 17 bar at 255 °C. If the vessel is cooled so that the pressure falls to 4.7 bar, determine the final pressure, heat transfer and change of entropy. Given Data: V1 = 0.25 m3 P1 = 17 bar = 1700 KN/m² T1 = 255°C = 528 K P2 = 4.7 bar = 470 KN/m² To find: 1) The final pressure 2) Heat transfer 3) Change of entropy

3. Air in a closed vessel of fixed volume 0.25 m³ exerts pressure of 17 bar at 255 °C. If the vessel is cooled
so that the pressure falls to 4.7 bar, determine the final pressure, heat transfer and change of entropy.
Given Data:
V1 = 0.25 m3
P1 = 17 bar = 1700 KN/m?
T1 = 255°C = 528 K
p2 = 4.7 bar = 470 KN/m²
To find:
1) The final pressure
2) Heat transfer
3) Change of entropy
