When a simple Rankine cycle is modified to include reheating for the same mass flowQuestion 1Select one:a.the pump work remains the same, the heat supplied is increased, the heat rejected is increased, the total turbine work increases, and the quality of steam leaving the turbine decreasesb.the pump work remains the same, the heat supplied is increased, the heat rejected stays the same, the total turbine work increases, and the quality of steam leaving the turbine decreasesc.the pump work remains the same, the heat supplied is increased, the heat rejected is increased, the total turbine work increases, and the quality of steam leaving the turbine increasesd.the pump work remains the same, the heat supplied remains the same, the heat rejected is increased, the total turbine work increases, and the quality of steam leaving the turbine increasese.the pump work remains the same, the heat supplied remains increases, the heat rejected stays the same, the total turbine work increases, and the quality of steam leaving the turbine increases

A simple ideal Rankine cycle operates between the pressure limits of 10 kPa and 4 MPa, with a turbine inlet temperature of 500C. The mass fraction of steam that condenses at the turbine exit is

The ideal vapour-compression refrigeration cycle is not a reversible cycle becauseQuestion 1Select one or more:a.heat input is not isothermal across an infinitesimal temperature differenceb.the ideal compression process is non-isentropicc.heat rejection is not isothermal across an infinitesimal temperature differenced.expansion process through the throttling valve is irreversiblee.phase changes that occurring during heat input and output cannot be reversed
