An inventor claims to have developed an engine that operates between a source at 450 K and a sink at 280 K, and is capable of delivering 0.15 kWh of work for every 1200 of heat received. As a patent officer, would you issue a patent for such an engine?
A power plant is operating with a heat-source reservoir at 350°C and a heat-sink reservoir at 30°C. It has a thermal efficiency equal to 55% of the Carnot-engine thermal efficiency for the same temperatures. To what temperature must the heat-source reservoir be raised to increase the thermal efficiency of the plant to 35%?
Prove that a refrigerator’s COP cannot exceed that of a completely reversible refrigerator that shares the same thermal energy reservoirs.
Consider a household refrigerator that uses HFC-134a as the refrigerant, operating between the pressures of 1.0 bar and 10 bars. Determine the enthalpy at each ofthe points 1, 2, 3, and 4, and calculate the coefficient of performance. Compare to the COP of a Carnot refrigerator operating between the same extreme temperatures. Does this temperature range seem reasonable for a household refrigerator? Explain briefly.

A refrigerator using R-134a as the refrigerant is used to keep a space at - 10°C by rejecting heat to ambient air at 22 °C. R-134a enters the compressor at 140 kPa as a saturated vapor and leaves at 800 kPa and 70 °C. The refrigerant leaves the condenser as a saturated liquid. The rate of cooling provided by the system is 2600 W. Determine (a) the mass flow rate of R-134a, (b) the COP, (c) the exergy destruction in each component of the cycle, (d) the second-law efficiency of the cycle, and (e) the total exergy destruction in the cycle.
Calculate and plot the COP of a completely reversible refrigerator as a function of the temperature of the sink up to 500 K with the temperature of the source fixed at 250 K.
A refrigerator that has a power (electric) input of 450W and a COP of 2.5 is to cool five large watermelons,10 kg each, to 8°C.
