1. An automobile engine has a Carnot thermal efficiency of 56.0% and an actual thermal efficiency of 21.0%. Determine the second law availability efficiency of this engine.

2. The turbine of a large power plant receives 1.00 × 108 Btu/h of heat from the boiler at 900.°F and rejects 5.50 × 106 Btu/h of heat to the condenser at 60.0°F while producing 22.0 × 103 kW of electrical power. The local environment (ground state) is at 14.7 psia and 50.0°F. Determine

a. The first law thermal efficiency.

b. The rate at which available energy enters the boiler.

c. The rate at which available energy enters the condenser.

d. The second law availability efficiency of the power plant.
