Saturated steam at 350 C is used to heat a countercurrent stream of methanol vapor from 70C to 300C in an adiabatic heat exchanger. The flow rate of methanol is 6000 L (STP) / min, and the steam condenses and leaves the exchanger as liquid water at 80C.

a) Calculate the necessary flow of the incoming steam in m 3 / min.

b) Calculate the heat flux transferred from water to methanol (kW).
