8.25. Saturated steam at 300°C is used to heat a countercurrently 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). anc mixture
