Steam is to be condensed on the shell side of a 1-shell-pass and 8-tube-passes condenser, with 50 tubes in each pass, at 30°C (hfg = 2431 kJ/kg). Cooling water (cp = 4180 J/kg·K) enters the tubes at 15°C at a rate of 1800 kg/h. The tubes are thin-walled, and have a diameter of 1.5 cm and length of 2 m per pass. If the overall heat transfer coefficient is 3000 W/m2·K, determine (a) the rate of heat transfer and (b) the rate of condensation of steam.

A jacketted-agitated vessel, fitted with a turbine agitator, is used for heating a water stream from 10°C to 54°C. The average heat transfer coefficient for water at the vessel’s inner-wall can be estimated from Nu = 0.76Re2/3Pr1/3. Saturated steam at 100°C condenses in the jacket, for which the average heat transfer coefficient in kW/m2·K is ho=5 13.1(Tg - Tw)20.25. The vessel dimensions are Dt = 0.6 m, H = 0.6 m and Da = 0.2 m. The agitator speed is 60 rpm. Calculate the mass rate of water that can be heated in this agitated vessel steadily.
Water enters a 2.5-cm-internal-diameter thin copper tube of a heat exchanger at 15oC at a rate of 0.61 kg/s, and is heated by steam condensing outside at 115oC.

A shell-and-tube process heater is to be selected to heat water (Cp = 4190 J/kg°C) from 20 °C to 90 °Cby steam flowing on the shell side. The heat transfer load of the heater is 600 kW. If the inner diameterof the tubes is 1 cm and the velocity of water is not to exceed 3 m/s, determine how many tubes needto be used in the heat exchanger.
In a once-through boiler, feedwater enters through the bottom og tubes, receives heat from combustion of coal, and escapes from the top of the tubes as superheated steam, calculate the heat transfer coefficients of water and superheated steam using the following data: Pressure of feedwater at tube inlet = 27.0 MPa Absolute temperature of feedwater, Tf =563 K Pressure of superheated steam at tube outlet = 24.5 MPa Absolute Temperature of superheated steam, Tg = 838 K Velocity of Feedwater through each tube.

The condenser of a steam power plant operates at a pressure of 0.95 psia. The condenser consists of 144 horizontal tubes arranged in a 12 * 12 square array. Steam condenses on the outer surfaces of the tubes whose inner and outer diameters are 1 in and 1.2 in, respectively. If steam is to be condensed at a rate of 6800 lbm/h and the temperature rise of the cooling water is limited to 8°F, determine (a) the rate of heat transfer from the steam to the cooling water and (b) the average velocity of the cooling water through the tubes.

Ethylene glycol is heated from 25°C to 40°C at a rate of 2.5 kg/s in a horizontal copper tube (k = 386 W/m·K) with an inner diameter of 2.0 cm and an outer diameter of 2.5 cm. A saturated vapor (Tg = 110°C) condenses on the outside-tube surface with the heat transfer coefficient (in kW/m2·K) given by 9.2/(Tg - Tw)0.25, where Tw is the average outside-tube wall temperature.
