Saturated steam at 300 c is used to heat countercurrently flowing stream of methanol vapor from 65c to 260 c in and 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 m^3/min. b) calculate the rate of heat transfer from the water to the methanol (kw).
