In a regenerative Rankine cycle. the closed feedwater heater with a pump as shown in the figure is arranged so that the water at state 5 is mixed with the water at state 2 to form a feedwater, which is a saturated liquid at 200 psia. Feedwater enters this heater at 350°F and 200 psia with a flow rate of 3 lbm/s. The bleed steam is taken from the turbine at 160 psia and 400°F and enters the pump as a saturated liquid at 160 psia. Determine the mass flow rate of the bleed steam required to operate this unit. Use steam tables. Feedwater Bleed steam (from turbine) [3 m m₁ The mass flow rate of the bleed steam required to operate the unit is Ibm/s.

In a steam plant operating according to an ideal Rankine cycle, water vapor enters the turbine at a pressure of 3.0 MPa and a temperature of 600 oC and exits the turbine with a dryness of 100 kPa and 0.8. By removing heat from the condenser to the surrounding environment, the water is provided to be saturated liquid at 100 kPa. In this case, what would be the amount of heat released from the Condenser to the surrounding environment per unit mass?
