Problem 4 Consider a gas power cycle executed in a closed system with 0.08 kg of gas. The gas is initially at 120 kPa, 2°C. First,910 kJ/kg of heat is added under constant volume. Then, more heat is added under constant pressure such that the gas reaches 1387°C. Then, the gas is expanded isentropically to 120 kPa. Finally, heat is rejected from the system under constant pressure such that it returns the gas to its initial state. Assuming air-standard cycle...

A monatomic ideal gas is taken through a closed cycle. Starting from state 1 with pressure P1 and volume V1 the gas expands isothermally (at constant temperature) to volume V2 = 2V1. It is then compressed at constant pressure back to the original volume V1 and then heated at constant volume to return to the original pressure P1 . a) Find how much work is performed by this gas during each part of this cycle. b) Find how much heat...

A Carnot cycle is conducted using an ideal diatomic gas. Initially, the gas is at temperature 25C., pressure of 100KPa and volume of 0.01m3. The system is then compressed isothermally to a volume 0.002m3. From that point, the gas undergoes an adiabatic compression ( with gamma= 1.4), until the volume further reduces to 0.001m3. After that, the system goes an isothermal expansion process to a point where the pressure of the system is 263.8KPa. Then the system continues the cycle...
