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.

Water (Cp = 4200 J/kg- °C) is used
cool an unknown fluid (with a given
Cp = 3810 J/kg.ºC) using a two-pass
parallel flow double-pipe heat

the heat exchanger at 66 °C with a
flowrate of 1.46 kg/s. Water can be
supplied at 10 °C and 1.32 kg/s. If the
heat exchanger cool the unknown
fluid to 39 °C, then the NTU of this
heat exchanger is equal to
O 0.79

Due higher viscosity, the heat-transfer coefficient of moving liquid hydrocarbons is generally higher than that of moving water Select one: O True O False The proper strategy to enhance heat transfer of a heat exchanger is trying to increase the heat transfer coefficient of the side with the lower heat resistant. Select one: O True O False For the universal 3-D heat transfer equation (see topic 7 in URCourses notes), we have to simplify by eliminating terms that are zero or near zero first, and then we can only use numerical methods (such as finite difference) to solve those problems.

A dairy farm needs to chill the milk from 39°C (extraction temperature is the same as the cow's body temperature) to at least 12°C for storage by using an existing 4-m long concentric-tube heat exchanger. The inner tube of the heat exchanger is 4 cm in diameter. The milk (density: 1035 kg/m³, specific heat: 3860 J/kg.K) flows into the heat exchanger at a rate of 270 liters per hour. On the cold side, there is a supply of water at 2°C at a rate of 0.23 kg/s. The estimated overall heat transfer coefficient of the heat exchanger is 1084.2 W/m².K. It was measured that the water comes out of the heat exchanger at 11°C. Is the milk indeed being cooled down to at least 12°C by heat exchanger as required by the farm? Looking at the temperatures obtained from your calculation, put an argument whether the heat exchanger is a parallel-flow or a counter-flow heat exchanger. Approximate specific heat of water is 4200 J/kg.K. Neglect radiation.
