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.

Question
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.
