Saturated steam at a gauge pressure of 2.0 bar will be used to heat a stream of ethane. the latter enters a heat exchanger at 16 ° c with a gauge pressure of 1.5 bar at a rate of 795 m3 / min and is heated to constant pressure up to 93 ° c. the water vapor condenses and leaves the exchanger as liquid at 27 ° c. the specific enthalpy of ethane at the given pressure is 941 kj / kg at 16 ° c and 1,073 kj / kg at 93 ° c. a) how much energy should be transferred to ethane to heat it from 16 ° c to 93 ° c? b) assuming that all the energy transferred from the steam is used to heat the ethane, how much vapor in m3 / s should be supplied to the exchanger?
