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.

Explain the role of the baffles in a shell-and-tube heat exchanger as well as how the presence of these baffles affects the heat transfer and the pumping power requirements?
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.
