Saturated steam at $300\mathrm{.}1C$ is used to heat a countercurrently flowing stream of methanol vapor from $65\mathrm{.}0C$ to $269\mathrm{.}7C$ in an

adiabatic heat exchanger. The flow rate of the methanol is $6530$ standard liters per minute, and the steam condenses and leaves the

heat exchanger as liquid water at $100\mathrm{.}0C.$
