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.

a one shell and two tube pass heat exchanger, coolant enters the tube at 4.81 kg/s (spread over 72 tubes with each tube being 0.01 m in diameter and 1.95 m length) at an initial temperature of 25 C. Water enters the shell at 2.5 kg/s at an initial temperature of 5 C. The average convection coefficient of the water is known to be 1e4 W/m2.K. What is the overall heat transfer coefficient, assuming no fouling, negligible tube thermal resistance and near-identical inner and outer tube surfaces? What is the actual heat transfer rate?

Q) Compare the heat transfer coefficients under the following conditions (Assume flow is turbulent). (1) Two fold increase in the diameter of the tube; the flow velocity is maintained constant by a change in the rate of liquid flow. (2) Two fold increase in the flow velocity by varying the mass flow rate. Comment on. the results.
A shell-and-tube heat exchanger is used to cool compressed liquid methanol from 176 °F to 104 °F. The methanol flows on the shell side of the exchanger. The coolant is water that rises in temperature from 50 °F to 86 °F and flows within the tubes at a rate of 68.9 kg s-1. Finding the appropriate thermophysical data and applying the proper equations, you are required to do the following:

A long, thin-walled double-pipe heat exchanger with tube and shell diameters of 0.01 m and 0.025 m, respectively, is used to condense refrigerant-134a with water at 20°C. The refrigerant flows through the tube, with a convection heat transfer coefficient of hi= 4100 W/m² °C. Water flows through the shell at a rate of 0.3 kg/s. The thermal resistance of the inner tube is negligible since the tube material is highly conductive and its thickness is negligible. Both the water and refrigerant-134a flows are fully developed. Properties of the water and refrigerant-134a are constant. Water properties: p = 998 kg/m³, v=u/p-1.004x 10-6 m²/s, k = 0.598 W/m. °C, Pr = 7.01 Cold water D Do
