Saturated steam at 300°C is used to heat a counter currently flowing stream of methanol vapor from 65°C to 260°C 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 90°C.

(a) Calculate the required flow rate of the entering steam in m3/min.

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