A stream of methanol vapor is used to chill a countercurrently flowing saturated steam in an adiabatic heat exchanger. Steam enters at 300C and exits as liquid water at 90C, while methanol enters at 5,500 STP L/min at 65C at and leaves at 260C.
(a) what is the flow rate of steam in m3/min?
(b) what is the rate of heat transfer (kW)?
