A shell and tube exchanger consists of a number of tubes mounted inside a cylindrical shell. Figure 1 illustrates a typical unit that may be found in a petrochemical plant. Two fluids can exchange heat, one fluid flows over the outside of the tubes while the second fluid flows through the tubes. A tube-in-tube heat exchanger is created by putting a small pipe into a larger pipe, and the assembly may be coiled to occupy less space. The water and the heat-transfer fluid flow in opposite directions to each other. This type of heat exchanger has two loops similar to those described in the shell-and-tube heat exchanger.

The Heat Exchanger Tube Weight Calculator formula to determine weight per foot is asfollows: Wt/ft = 10.69 (outer diameter - wall thickness)*wall thickness. As per the ASTM calculation, it is assumed thatthe tube manufactured has consistent wall thickness. Note that the actual wallthickness is always thicker than the minimum one specified.

Calculating Heat Exchanger Efficiency For any system, efficiency is normally calculated by comparing the actual performance with ideal performance. Efficiency = Actual output / Output of the ideal system Since we don't have an ideal heat exchanger to compare with, we cannot use the traditional concept of efficiency for heat exchangers.
