counterflow double-pipe heat exchanger is used to heat water from 20 deg * C to 40 deg * C with ahot oil which enters the exchanger at 180 deg * C and leaves at 140 deg * C The flow rate of wateris 3.0 kg/s and the overall heat-transfer coefficient is 200 W/m2.K. Assume the specificheat for oil is 2100 J/ kg .K. Suppose the water flow rate is cut in half. 1. What new oil flow rate would be necessary to maintain a 40 deg * C outlet watertemperature?

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.
