Saturated steam at $342\mathrm{.}1C$ is used to heat a countercurrently flowing stream of methanol vapor from $70\mathrm{.}0C$ to $301\mathrm{.}7C$ in an

adiabatic heat exchanger. The flow rate of the methanol is $7530$ standard liters per minute, and the steam condenses and leaves the

heat exchanger as liquid water at $90\mathrm{.}0C.$
