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

Water flows at 1 kg/s in a 10 mm diameter tube and is to be heated from 25 to 75 ° C. The
tube surface temperature is maintained at 100 °C.
Using the following properties for the water:
p= 998 kg/m?, Cp = 4171 J/kg K, k = 0.651 W/m K, µs = 4.71 x 104 kg/m s,
Hw = 2.82 x 104 kg/m s and Pr = 3.02.
a) What is the required tube length for these conditions?
b) To design a water heating system, consider using tube diameters in the range from
10 to 30 mm. What are the required tube lengths for water flow rate of 1 kg/s? Plot
the tube length as a function of tube diameter.
c)
Plot the pressure gradient as a function of the tube diameter for the given water flow
rate of 1 kg/s. Assume tube wall is smooth.
