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 90°F (hfg = 1043 Btu/lbm). Cooling water (cp = 1.0 Btu/lbm·°F) enters the tubes at 60°F and leaves at 73°F. The tubes are thin walled and have a diameter of 3/4 in and length of 5 ft per pass. If the overall heat transfer coefficient is 600 Btu/h·ft2·°F, determine (a) the rate of heat transfer, (b) the rate of condensation of steam, and (c) the mass flow rate of cold water.
Heat Exchangers
Heat exchangers are the types of equipment that are primarily employed to transfer the thermal energy from one fluid to another, provided that one of the fluids should be at a higher thermal energy content than the other fluid.
Heat Exchanger
The heat exchanger is a combination of two words ''Heat'' and ''Exchanger''. It is a mechanical device that is used to exchange heat energy between two fluids.
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 90°F (hfg = 1043 Btu/lbm). Cooling water

transfer, (b) the rate of condensation of steam, and (c) the
mass flow rate of cold water.
