Water is the working fluid in an ideal regenerative Rankine cycle with one closed feedwater heater. Steam enters the turbine at 1400 Ibp/in.² and 1000°F and expands to 120 lb/in.2, where some of the steam is extracted and diverted to the closed feedwater heater.

Question 15 of 15 View Policies Current Attempt in Progress Water is the working fluid in a regenerative Rankine cycle with one closed feedwater heater and one open feedwater heater. Steam enters the turbine at 1400 lbf/in.2 and 950°F and expands to 400 lbf/in.2, where part of the steam is extracted and diverted into the closed feedwater heater. Condensate exiting the closed feedwater heater as saturated liquid at 400 lbf/in.2 is trapped into the open feedwater heater operating at 140 lbf/in.² The feedwater leaves the closed feedwater heater at 1400 lbf/in.² and a temperature equal to the saturation temperature at 400 lbf/in.² The remaining steam expands through the second-stage turbine to 140 lbf/in.2, where some of the steam is extracted and diverted to the open feedwater heater.

6 Water is the working fluid in an ideal regenerative Rankine cycle with one open feedwater heater. Steam enters the turbine at 1400 lbf/in.2 and 1000°F and expands to 120 lbf/in.2, where some of the steam is extracted and diverted to the open feedwater heater operating at 120 lbf/in.2 The remaining steam expands through the second-stage turbine to the condenser pressure of 6 lbf/in.2 Saturated liquid exits the open feedwater heater at 120 lbf/in.2 The net power output of the cycle is 1 x 108 Btu/h.Determine for the cycle:(a) the mass flow rate of steam entering the first stage of the turbine, in lb/h.(b) the rate of heat transfer, in Btu/h, to the working fluid passing through the steam generator.(c) the percent thermal efficiency.
