To successfully design a heat exchanger, use the sliders to set the inner diameter, thickness and length of the tubes. Then the Demonstration computes several important design variables:

• exchanger heat duty (in kW)

• log mean temperature difference (LMTD) (in )

• correction factor

• shell diameter (in meters)

• bundle diameter (in meters)

• outer diameter of the tubes (in millimeters)

• required exchange surface area (in )

• number of tubes per pass

• tube-side and shell-side pressure drops and (in kPa)

• overall heat transfer coefficient

• baffle spacing (in meters)

• tube-side and shell-side heat transfer coefficients and

Here, we assume a heat exchanger with one shell pass and two tube passes. Additionally, a split-ring floating head type is adopted in order to find the bundle diametrical clearance. The tube is made of copper. Details of the calculation procedure are available in [1]. Note that the values found for as well as and should be among the necessary criteria for a good design.
