What are the four processes of the Carnot cycle?
What is the Carnot cycle?
A gas turbine cycle with a stage of reheat and regeneration operates under the conditions given below, as illustrated in the figure. The turbine efficiencies are 86%, and the compressor efficiency is 81%. Furthermore, the work output of the high-pressure turbine is just enough to drive the compressor. Determine the pressure at which the reheater operates. T1 = 1300 K, T6 = 3000 K, P1 = 450 kPa, P6 = 100 kPa
Explain why a certain amount of thermal energy rejected intentionally incondensers and pumps are employed instead of compressors in steam power cycles?
The 7FA gas turbine manufactured by General Electric is reported to have an efficiency of 35.9 percent in the simple-cycle mode and to produce 159 MW of net power. The pressure ratio is 14.7 and the turbine inlet temperature is 1288°C. The mass flow rate through the turbine is 1,536,000 kg/h. Taking the ambient conditions to be 20°C and 100 kPa, determine: (a) the isentropic efficiency of the turbine and the compressor, (b) the thermal efficiency of this gas turbine if a regenerator with an effectiveness of 80 percent is added. Answers: (a) 0.849, 0.924 (b) 0.496
Can you show that the thermal efficiency of Stirling cycle is identical to the thermal efficiency of Carnot cycle for same temperature limits? State your assumptions.

A gas-turbine-powered Plymouth car built in 1960 had a turbine inlet temperature of 1700°F, a pressure ratio of 4, and a regenerator effectiveness of 0.9. Using isentropic efficiencies of 80 percent for both the compressor and the turbine, determine the thermal efficiency of this car. Also, determine the mass flow rate of air for a net power output of 130 hp. Assume the ambient air to be at 510 R and 14.5 psia.
Consider a steady-state steam turbine. Steam enters the turbine at a pressure of 12.5??? and a temperature of 700℃, and leaves the turbine at a pressure of 0.5???. If the isentropic efficiency of this turbine is 86%, determine its second law efficiency.
Water enters the boiler of a steady-flow Carnot engine as a saturated liquid at 400 psia and leaves with a quality of 0.95. Steam leaves the turbine at a pressure of 20 psia. Show the cycle on a T-s diagram relative to the saturation lines, and determine (a) the thermal efficiency, (b) the quality at the end of the isothermal heat-rejection process, and (c) the net work output.
Try to explain why a certain amount of thermal energy rejected intentionally in condensers and pumps are employed instead of compressors in steam power cycles?
