Consider a liquid (Cp = 2.2 kJ /kg·K) is cooled at a rate of 12 kg/min from 150°C to 40°C in the tube side of a double-pipe counterflow heat exchanger. Water (Cp = 4.18 kJ /kg·K) enters the heat exchanger at 10°C at a rate of 9 kg/h. The outside diameter of the inner tube is 2.5 cm, and its length is 6.0 m. Calculate the overall heat transfer coefficient. (Answer: U = 2.31 kW/m2·K)

Question
Consider a liquid (Cp = 2.2 kJ /kg·K) is cooled at a rate of 12 kg/min from 150°C to 40°C in the tube side of
a double-pipe counterflow heat exchanger. Water (Cp = 4.18 kJ /kg·K) enters the heat exchanger at 10°C at
a rate of 9 kg/h. The outside diameter of the inner tube is 2.5 cm, and its length is 6.0 m. Calculate the overall
heat transfer coefficient. (Answer: U = 2.31 kW/m2·K)
