Problem 2 Consider a reheat Rankine cycle utilizing steam. Steam leaves the boiler and enters the turbine at 600 psia, 800 °F. After expansion in the turbine to 60 psia, the steam is reheated to 800 °F and then expanded in the low-pressure turbine to 1 psia. After presenting a schematic of the problem in addition to clearly labeled and explained T-s and h-s diagrams, you are asked to determine the following: (a) Pump work required per Ibm of working fluid. Quality of fluid at turbine inlet. (b) (d) (e) (f) Work output of turbine per Ibm of working fluid. Energy input to the boiler per Ibm of working fluid. Heat rejection by the condenser per Ibm of working fluid. Determine the cycle thermal efficiency.

An ideal Rankine cycle operates between a steam boiler pressure of 18 MPa and a condenser temperature of 42 °C. The steam leaving the boiler is a saturated vapor. The net power generated by the cycle is 150 MW. What is the mass flow rate of steam? What is the cycle efficiency? Use the formula: n=Wnet/Qin.

A Brayton cycle is used to estimate the performance of an aircraft engine with nitrogen as the working fluid. The engine generates a net power of 10 MW. Nitrogen enters the compressor of the engine at 250 K and 80 kPa and is compressed to a pressure of 400 kPa. The gas exits the turbine of the engine at 450 K and 80 kPa.a.

The following is how a reheat turbine works. It takes steam with a pressure of 1560 psi and a temperature of 780 F and expands it to 430 psi. The steam now returns to the boiler to be resuperheated before returning to the turbine at 410 psi and 600 F. The steam then expands to the condenser temperature of 96 F. Calculate the efficiency of the cycle.
5. Consider a steam power plant operating on the ideal Rankine cycle. The steam enters the turbine at 5 MPa, 350 °C and is condensed in the condenser at a pressure of 15 kPa. Determine the thermal efficiency of the cycle if the steam were superheated to 750 °C. Draw the schematic and Ts diagram.
