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 (h_fg= 1043 Btu/lbm). Cooling water (c_p= 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,

(c) The mass flow rate of cold water.
