Enter the heat transfer coefficient, plate area, and the log mean temperature differential into the calculator to determine the plate heat exchanger capacity.

Plate Heat Exchanger Capacity Formula

The following equation is used to calculate the Plate Heat Exchanger Capacity.

C = k * A* LMTD

  • Where C is the Plate Heat Exchanger Capacity (btu/h)
  • k is the heat transfer coefficient (btu/ft^2*h*f)
  • A is the surface area of the plate (ft^2)
  • LMTD is the log mean temperature difference (f)

To calculate the Plate Heat Exchanger Capacity, multiply the heat transfer coefficient by the surface area, then multiply that result by the log mean temperature difference.

What is a Plate Heat Exchanger Capacity?

Definition:

A Plate Heat Exchanger Capacity is a measure of the total heat load per unit time a heat exchange can remove or exchange from a system.

How to Calculate Plate Heat Exchanger Capacity?

Example Problem:

The following example outlines the steps and information needed to calculate Plate Heat Exchanger Capacity.

First, determine the heat transfer coefficient. In this example, the heat transfer coefficient is measured to be 12.56 BTU/ft^2*h*F

Next, determine the total surface area of the plate. This is calculate to be 10ft^2.

Next, determine the log mean temperature difference. With the help of the calculator linked above, this is found to be 50 F.

Finally, calculate the Plate Heat Exchanger Capacity using the formula above:

C = k * A* LMTD

C = 12.56* 10* 50

C = 6,280 BTUs/hr
