Counter Flow Heat Exchanger Calculator

The currently calculating value will always be highlighted in green.

Counter flow heat exchanger calculator.

A box will be highlighted yellowif it needs input. Input data in yellow update and reset funtions at bottom of page. Lmtd calculation calculate log mean temperature difference lmtd for shell and tube exchanger for counter current and co current flow. Heat exchanger calculations with the heat exchanger design equation require a value for the heat transfer rate q which can be calculated from the known flow rate of one of the fluids its heat capacity and the required temperature change.

A counter flow heat exchanger is one in which the direction of the flow of oneof the working fluids is opposite to the direction to the flow of the other fluid. In a parallel flowexchanger both fluids in the heat exchanger flow in the same direction. The number of transfer units ntu method is used to calculate the rate of heat transfer in heat exchangers especially counter current exchangers when there is insufficient information to calculate the log mean temperature difference lmtd. Enter the fluid data and enter 5 of the 6 available inputs under flow rates and temperatures.
