Consider a shell and tube heat exchanger which is used to heat water (Cp, water = 4.33kJ/(kgK)) from 10 deg C to 85 deg C flowing in the tube at the rate 7kg/s. For heating of water, hot oil (Cp, oil = 2.34 kJ/(kg*K)) is used which is flowing in the shell at the rate 14 kg/s and enters the heat exchanger at 155 deg C. Determine exit temp of oil and heat transfer rate between oil and water. Consider water and liquid as incompressible liquids and heat exchanger as very well insulated.
