Water enters at 110 ℃ at a rate of 2 kg/s in a double-pipe parallel flow heat exchanger to heat a chemical whose inlet temperature is 20 ℃ and at a rate of 3 kg/s. The overall heat transfer coefficient of the heat exchanger is 1200 W/m2. ℃. The heat transfer surface area of the heat exchanger is 7.6 m2. What is the actual heat transfer rate of the heat exchanger? The specific heats of the water and chemical are given to be 4.18 and 1.8 kJ/kg.℃, respectively. Select one: a. 277 kW b. 255 kW c. 207 kW d. 305 kW
