The states must be arranged in a chronological order; c.Plot each cycle in a t-s diagram with the states consistent to the states assignment in the schematic diagram; d.Show a detailed solution. Consider a regenerative vapor power cycle with a single open feedwater heater. Steam enters the first turbine stage at 12MPa, 500 0C, and expands to 0.3MPa where some steam is extracted and fed to the feedwater heater. The remainder expands through the second-stage turbine and exits at the condenser pressure of 0.01 MPa. Saturated liquid at 0.3 MPa leaves the open feedwater heater. If the net power output of the cycle is 100 MW,and the turbine stages and pumps are isentropic, determine (a) the thermal efficiency, and(b) the mass flow rate of steam entering the first turbine, in kg/h.

Which statement/s are true? Heat is transferred to a system by either an air-sourced Carnot heat pump, an electrical resistance heater or a heat source at temperature marginally higher than the system temperature. The loss of Carnot Work Potential (Exergy destruction, or T0Sloss term) is minimum when heat is added by the air-sourced Carnot heat pump. Heat is transferred to a system either by an 100% efficient electrical resistance heater, or an 100% efficient isothermal heat source. The loss of Carnot Work Potential (Exergy destruction, or T0Sloss term) is zero when heat is added by the isothermal heat source. Heat is transferred to a system by either an air-sourced Carnot heat pump, an electrical resistance heater, or a heat source at temperature marginally higher than the system temperature.
