Cold water (cp 5 4180 J/kg?K) enters the tubes of a heat exchanger with 2-shell passes and 20-tube passes at 208C at a rate of 3 kg/s, while hot oil (cp 5 2200 J/kg?K) enters the shell at 1308C at the same mass flow rate and leaves at 608C. 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 and (b) the heat transfer surface area on the outer side of the tube.
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.
Cold water (cp 5 4180 J/kg?K) enters the tubes of a
heat exchanger with 2-shell passes and 20-tube passes at 208C
at a rate of 3 kg/s, while hot oil (cp 5 2200 J/kg?K) enters the
shell at 1308C at the same mass flow rate and leaves at 608C.
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 and (b) the heat transfer surface area on the outer side
of the tube.
