Concept explainers

Heat Exchangers

Heat exchangers are the types of equipment that are primarily employed to transfer the thermal energy from one fluid to another, provided that one of the fluids should be at a higher thermal energy content than the other fluid.

Heat Exchanger

The heat exchanger is a combination of two words ''Heat'' and ''Exchanger''. It is a mechanical device that is used to exchange heat energy between two fluids.

Question

Problem 3
Oil(light) enters a heat exchanger at 450 K with a mass flow rate of 10 kg/s and exits at
350 K. A separate stream of liquid water enters at 20°C, 500 kPa. Each stream
experiences no significant change in pressure. Stray heat transfer with the
surroundings of the heat exchanger and kinetic and potential energy effects can be
ignored. If no water vapor is to be present in the exiting water stream, what is the
minimum mass flow rate for the water?
