Question:

Consider an ideal air-standard Ericsson cycle that has an ideal regenerator as shown in Fig. P11.62, the high pressure is 1 MPa and the cycle efficiency is 70%. Heat is rejected in the cycle at a temperature of 300 K, and the cycle pressure at the beginning of the isothermal compression process is 100 kPa.
