An ideal regenerative engine receives 140,000 kg/hr of throttled steam at 15 MPaa and 600 °C. Before condensation at 10 kPaa, the steam is extracted for feedwater heating first at 2 MPaa and the second at 1 MPaa. Determine: a) mass of extracted steam in kg/hr, b) ideal power developed by the engine (kW), b) ideal total power required by the pump, c) heat transferred in the boiler and condenser (kW), d) steam rate of the cycle (kg/kw-hr), e) thermal efficiency of the engine, f) thermal efficiency of the cycle, g) Heat rate
