Counter Flow Heat Exchanger Calculator

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.

Input data in yellow update and reset funtions at bottom of page. Enter the fluid data and enter 5 of the 6 available inputs under flow rates and temperatures. The currently calculating value will always be highlighted in green. In heat exchanger analysis if the fluid inlet and outlet temperatures are specified or can be determined by simple energy balance the lmtd method can.

The simplest heat exchanger is one for which the hot and cold fluids move in the same or opposite directions in a concentric tube or double pipe construction.

Lmtd calculation calculate log mean temperature difference lmtd for shell and tube exchanger for counter current and co current flow. Figure 9 represents the directions of fluid flow in the parallel and counter flow exchangers. A box will be highlighted yellowif it needs input. Counter parallel flow heat exchanger tube length calculation.

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 the parallel flow arrangement of figure 18 8 a the hot and cold fluids enter at the same end flow in the same direction and leave at the same end.
