Saturated steam at 300C is used to heat a countercurrently flowing stream of methanol vapor from 65C to 260C in an adiabatic heat exchanger. The flow rate of the methanol is 5500 standard liters per minute, and the steam condenses and leaves the heat exchanger as liquid water at 90C.

(a) Calculate the required flow rate of the entering steam in m/min.

(b) Calculate the rate of heat transfer from the water to the methanol (kW).
