Question:
A thin-walled double-pipe counter-flow heat exchanger is to be used to cool oil (cp = 2200 J/kg·K) from 150°C to 40°C at a rate of 2 kg/s by water (cp = 4180 J/kg·K) that enters at 22°C at a rate of 1.5 kg/s. The diameter of the tube is 2.5 cm, and its length is 6 m. Determine the overall heat transfer coefficient of this heat exchanger.
