Consider a reheat Rankine cycle in which the steam enters the high-pressure turbine at 7 MPa and 500°C. After the expansion process in the high-pressure turbine to 400 kPa, the steam is reheated to 500°C in the boiler and then expanded in the low-pressure turbine to 7.5 kPa. Assume that saturated liquid enters the pump, and pumping and expansion processes are isentropic. Calculate the thermal efficiency of the cycle, in %.

Basic Thermodynamic Processes

The word 'thermodynamics' can be divided into two words, 'thermo' and 'dynamics'. The word thermo deals with the heat and thermal phenomenon, whereas dynamics deals with forces or external agent that drives the heat flow or aids in the motion of heat.

Question

thermodynamics

Consider a reheat Rankine cycle in which the steam enters the high-pressure turbine at 7 MPa and
500°C. After the expansion process in the high-pressure turbine to 400 kPa, the steam is reheated to
500°C in the boiler and then expanded in the low-pressure turbine to 7.5 kPa. Assume that saturated
liquid enters the pump, and pumping and expansion processes are isentropic. Calculate the thermal
efficiency of the cycle, in %.
