10-14 A small shell-and-tube exchanger with one tube pass [A = 4.64 m 2 and U = 280 W/m 2 · °C] is to be used to heat high-pressure water initially at 20 °C with hot air initially at 260 °C. If the exit water temperature is not to exceed 93 °C and the airflow rate is 0.45 kg/s, calculate the water-flow rate.
