Question:

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 (h_fg= 2431 kJ/kg). Cooling water (c_p= 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

(b) The rate of condensation of steam.
