A stream of hydrocarbon (cp = 2.2 kJ/kg·K) is cooled at a rate of 720 kg/h from 150°C to 45°C in the tube side of a double-pipe counter-flow heat exchanger. Water (cp = 4.18 kJ/kg·K) enters the heat exchanger at 10°C at a rate of 540 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. (Round the answer to two decimal places.) The overall heat transfer coefficient is _____ kW/m2·K.
