Evaporation:

Saturated steam at 25 psia enters a surface condenser cooled directly by spraying water entering at 80 F. If the combined condensed steam and water leaves the condenser at 200 F, determine the required cooling water in lb/hr.

ans. 4130 lb/hr

A saturated solution of potassium chloride at 90 °C containing 700 kg potassium chloride is cooled to 20 °C in an open tank by circulation of water. The cooling water enters the tank at 15 °C through a jacket and leaves at 25 °C. The solubility of potassium chloride is 53.9 and 34.2 gm/100ml of water at 90 and 20 °C respectively, The average specific heat and density of the solution are 0.48 cal/g.°C and 1.2 g/cm', respectively. Assuming the...

Saturated water vapor leaves a steam turbine at a flow rate of 1.47 kg/s and a pressure of 0.51 bar. The vapor is to be completely condensed to saturated liquid in a shell-and-tube heat exchanger that uses city water as the cold fluid. The water enters the thin-walled tubes at 17oC and is to leave at 57.6 oC. Assuming an overall heat transfer coefficient of 2000 W/m2K, determine the required heat exchanger surface area and the water flow rate. cp,c...

An air-cooled steam condenser is operated with air in cross flow over a square, in-line array of 400 tubes (NL=NT= 20), with an outside tube diameter of 20 mm and longitudinal and transverse pitches of SL= 60 mm and ST= 42 mm, respectively. Saturated steam at a pressure of 2.455 bars enters the tubes, and a uniform tube outer surface temperature of Ts= 390 K may be assumed to be maintained as condensation occurs within the tubes. (a) If the...

A fired boiler is used to produce thirty thousand lbm/hr of saturated (vapor) steam at 200 psia, from liquid water which enters at 70 degrees F. Natural gas (assume pure methane) is used for fuel with 10% excess air. Assuming complete combustion, with exhaust flue gas leaving at 500 degrees F, and constant Cp values (evaluated at room temperature), determine: a) the new power that can be produced in a Rankine cycle given the following conditions: * Turbine and pump...

Water is the working fluid in a regenerative Rankine cycle with one closed 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 closed feedwater heater. The remaining steam expands through the second-stage turbine to the condenser pressure of 3.5 lbf/in.2 Each turbine stage and the pump have isentropic efficiencies of 85%. Flow through the condenser, closed feedwater heater, and steam generator is...
