Water at 172°F is vaporized "in a cross-flow double tubeexchanger" at a rate of 0.11 lb/s by hot oil Cp = 0.95Btu/lb°Fentering at 240°F if the heat transfer surface area and the totalheat transfer coefficient are 70ft2 and 10Btu/ft2h°C,respectively.
Determine
a) The outlet temperature in °F
b) The mass rate of oil in pounds per minute.
