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).

How do temperature and salinity affect deepwater currents? as temperatures and salinity levels of water increase, the water rises to the surface where it creates currents as it moves to colder regions. they create changes in wind direction, moving denser water in the same direction as the wind and causing the deepwater circulation patterns found in the ocean. they equalize the forces on undersea currents caused by the coriolis effect as they replace more dense water with less dense water. they create density differences that cause dense deepwater currents to flow toward the equator where they displace less dense, warmer water above them.
