Concept explainers

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.

Textbook Question

Chapter 9, Problem 9.25PP

Refer to the shell-and-tube heat exchanger shown in Fig. 9.13. The outer tube has an OD of 7 / 8 in and the OD

of the inner tube is 1 / 2 in. Both tubes are standard steel tubes with 0.049 -in wall thicknesses. The inside tube carries 4.75 g a l / m i n of water at 200 ° F and the shell carries 30.0 g a l / m i n of ethylene glycol at 77 ° F to carry heat away from the water. Compute the Reynolds number for the flow in both the tube and the shell.

Did you assume that the pressures in fluid are the same in a horizontal plane even though they are in different tubes? Are the calculated pressures in a column of fluid always higher at lower elevations? Did you account for the fact that the two horizontal tubes of the U-tube are above the ground? Concepts: The pressure in a fluid is a function of the specific weight of the fluid and the height relative to a reference. Pressure is constant in a horizontal plane of a continuous mass of fluid. (a) What is the initial pressure difference? (PA-PB) (b) What is…
