Cold water (c p = 4180 J/kg K) enters the tubes of a heat exchanger with 2-shell
Question:
Cold water (cp = 4180 J/kg· K) enters the tubes of a heat exchanger with 2-shell passes and 20-tube passes at 20°C at a rate of 3 kg/s, while hot oil (cp = 2200 J/kg · K) enters the shell at 130°C at the same mass flow rate and leaves at 60°C. If the overall heat transfer coefficient based on the outer surface of the tube is 220 W/m2 · K, determine
(a) The rate of heat transfer
(b) The heat transfer surface area on the outer side of the tube.
