1. Find efficiency of a reversible power cycle consisting of two isochoric and two isobaric lines, if temperature is increased by a factor of n during the isochoric heating process and by the same factor n during the isobaric expansion process. The working fluid involved in the cycle is an ideal gas with isentropic exponent k. The answer must be expressed in terms of n and k only. Show the process on the P- V diagram.

1.On a pV diagram, draw the path a gas takes as it goes through the following processes: first it undergoes an isochoric heating process, then that’s followed by an isobaric cooling process, finally it goes back to its original position on the pV diagram by undergoing an isothermal expansion. 2. An ideal gas initially at volume V1, pressure P1, and temperature T1 undergoes an isobaric process that changes its temperature to T2. The gas immediately undergoes an isothermal process that...

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...
