An Ideal Reheat Rankine Cycle Operates Between the Pressure Limits

Multiple Choice

An ideal reheat Rankine cycle operates between the pressure limits of 20 kPa and 10 MPa, with reheat occurring at 3 MPa. The temperature of steam at the inlets of both turbines is 500°C, and the enthalpy of steam is 3027 kJ/kg at the exit of the high-pressure turbine, and 2385 kJ/kg at the exit of the low-pressure turbine. Disregarding the pump work, the cycle efficiency is

A) 26%
B) 32%
C) 57%
D) 40%
E) 60%
