A regenerative vapor power cycle has two turbine stages with steam entering the first turbine stage at 12 MPa, 600oC and expands to 1 MPa, where some of the steam is extracted and diverted to the open feed water heater operating at 1 MPa. The remaining steam expands through the second turbine stage to a condenser at pressure of 6 kPa. Saturated liquid exits the open feed water heater at 6 kPa. Each turbine stage and pump has an isentropic efficiency of 80%. The mass flow rate into the first turbine stage is 100 kg/s. Determine
(a) The thermal efficiency (ηth) of the cycle,
(b) The heat transfer to the steam in the steam generator.
(c) The net power developed and
