A system executes a power cycle while receiving 1050 kJ by heat transfer at a temperature of 525 K and discharging 700 kJ by heat transfer at 350 K. There are no other heat transfers.
a) Determine whether the cycle is internally reversible, irreversible, or impossible.b) Determine the thermal efficiency using the given heat transfer data. Compare this value with the Carnot efficiency and comment on it.
