Consider a heat exchanger in which heat from hot air will be used to heat a stream of carbon tetrachloride (CCl4) from 20C to 9.7C below its normal boiling point. The flow rate of air is 448 L (STP)/s, the air enters the heat exchanger at 700C and leaves the heat exchanger at 500C. (a) Prepare an enthalpy table and determine the flow rate of CCl4 (kg/s)
