PROBLEMS
6.1 2520 kg/ h of oil is to be cooled from 180 "C to 110 "C in a countercurrent heat
exchanger as shown in the figure below. Calculate the flow rate of water passing
through the heat exchanger for the following cases:
a) The cooling water, which enters the heat exchanger at 15"C, is mixed with
water at 30 "C at the exit of the heat exchanger to obtain 2415 kg/ h of process
water at 60°C to be used in another location of the plant.
b) The cooling water, which enters the heat exchanger at 30"C, is mixed with
water at 30°C at the exit of the heat exchanger to obtain 2415kg/ h of process
water at 60 "C to be used in another location of the plant.
