industrial power plant requires 3.301 lb of dry saturated steam
per second at 329 F for a heating pur
poses. This steam
may be supplied from an extraction turbine which receives steam at
27,580 psi and 716 F and is
exhausted to a condenser at the rate of 1.76 lb/s of steam at 23.44
psi while
rejecting 4,776,999.00 Btu/hr to the cooling tower. If the
mechanical efficiency of the
turbine- generator is 95% and that the heat loss in the turbine
casing is 34,121.00 Btu/Hr, Calculate h
e power generated by the plant.

(25) 7. A steam power plant operates on the Rankine cycle with steam entering the high pressure turbine at 1500 psi, 1000'C with a mass flow rate of 5x10lb/hr. The steam exits the high pressure turbine at 90 psi, 350°F where the steam is then sent back to the boiler and reheated to 900°F before expanding through the low pressure turbine to 1 psi. Cooling water enters the condenser from a lake at 65°F and exits at 90°F Assume...

A steam power plant operates with a maximum pressure of 3750 psia, maximum temperature of 1110 oF, and condenser pressure of 5 psia. There is a closed feedwater heater with stream extraction pressure of 100 psia with throttled condensate, and an open feedwater heater at a pressure of 700 psia. Assume isentropic turbomachinery. Determine Determine the mass fraction of steam extracted for each feedwater heater. Turbine work in Btu/lb Pump work in Btu/lb Heat addition in steam generator in Btu/lb...

1. An industrial plant needs 20,000 lbm of saturated steam at 280°F per hour for heating purposes and ten MW of electrical power. A small turbine system is to be designed to handle both of these needs. Steam is supplied to a turbine at 400 psia pressure from a boiler and expanded until 280°F saturated steam is obtained whereupon the steam needed for heating is extracted. The rest of the steam is expanded in a second turbine to a condenser...

Water is the working fluid in a Rankine cycle. Steam exits the steam generator at 1500 lbf/in.2 and 1100°F. Due to heat transfer and frictional effects in the line connecting the steam generator and turbine, the pressure and temperature at the turbine inlet are reduced to 1400 lbf/in.2 and 1000°F, respectively. Both the turbine and pump have isentropic efficiencies of 95%. Pressure at the condenser inlet is 2 lbf/ in. 2, but due to frictional effects the condensate exits the...
