Consider a Rankine cycle with reheat in which steam enters the high-rate turbine at 500 psi and 1000 F from which it expands to 120 psi; the latter reheats to 1000 F expanding to 2 psi in the low- rate turbine. Calculate the thermal efficiency of the cycle 500 psia, 1000 F 120 psia 1000 F 2 psia
A steam Rankine cycle operates between the pressure limits of 1500 psia in the boiler and 3 psia in the condenser. The turbine inlet temperature is 800°F. The turbine isentropic efficiency is 90 percent, the pump losses are negligible, and the cycle is sized to produce 2500 kW of power. How much error is caused in the thermal efficiency if the power required by the pump were completely neglected? Use steam tables. The error caused in the thermal efficiency if the power required by the pump was completely neglected is %.
Q4) Steam generated in a power plant at a pressure of 5500 kPa and a temperature of 420°C is fed to a turbine. Exhaust from the turbine enters a condenser at 20 kPa where it is condensed to saturated liquid, which then pumped to the boiler. Determine the thermal efficiency of a Rankin cycle operating at these conditions.
Consider a steam power plant, which can be modeled using the ideal reheat Rankine cycle. The steam entering the high- pressure turbine is at 6 MPa and 400 degrees C and leaves at 2 MPa.
