Question

A Rankine cycle works with water as the working fluid and operates between pressure limits of 5MPa in the boiler and 20kPa in the condenser and temperature at the turbine inlet of 600° C. Point 3 is saturated vapor, while Point 4 is saturated liquid. The pump works in a reversible adiabatic way. The boiler is designed to give a steam flow of 3kg / s. Determine the following, do all the necessary operations and write them down step by step. Make the T-s diagram explicitly. a) Pump work (kJ / s) b) Turbine efficiency (%) c) Thermal efficiency of the cycle (%) d) Q_capacitor (kJ / s) |
