As shown in Fig. P5.93, a system executes a power cycle
Chapter 5, Problem 5.93(choose chapter or problem)
As shown in Fig. P5.93, a system executes a power cycle while receiving 750 kJ by heat transfer at a temperature of 1500 K and discharging 100 kJ by heat transfer at a temperature of 500 K. Another heat transfer from the system occurs at a temperature of 1000 K. Using Eq. 5.13, plot the thermal efficiency of the cycle versus \(\sigma_{\text {cycle }}\), in kJ/K.
