An ideal Stirling engine using helium as the working fluid
Chapter 9, Problem 970(choose chapter or problem)
An ideal Stirling engine using helium as the working fluid operates between temperature limits of 300 and 2000 K and pressure limits of 150 kPa and 3 MPa. Assuming the mass of the helium used in the cycle is 0.12 kg, determine (a) the thermal efficiency of the cycle, (b) the amount of heat transfer in the regenerator, and (c) the work output per cycle.

ANSWER:Step 1 of 4
An ideal Stirling engine with helium as the working fluid operates between the specified temperature and pressure limits.
The thermal efficiency of the cycle, the amount of heat transfer in the regenerator, and the work output per cycle are to be determined.We assume that the Helium is an ideal gas with constant specific heats.The gas constant and the specific heat of helium at room temperature are
