Afruit drying system consists of a fan followed by a heat exchanger. air at 20°c enters the fan, which supplies 200 kg/s while consuming 90 kw of power (i. e. doing work on the air at a rate of 90 kw). the air exits the heat exchanger at 75°c. the heat is supplied by steam, which enters as saturated vapor and exits as saturated liquid at 500 kpa. determine: 2. a. the temperature of air after the fan, in oc b. the rate of heat transfer from the steam to the air, in kw c. the steam mass flow rate, in kg/s
