Counter Flow Heat Exchanger Calculator

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.

Counter flow heat exchanger calculator.

Counter parallel flow heat exchanger tube length calculation. 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. Plane wall heat transfer coefficient u 1 1 ho l k 1 h1. 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.

Following is the equation to be used. Heat transfer calculator to approximate the results of a heat transfer system. Q m h c ph t hin t hout m c c pc t cout t cin where. In a parallel flowexchanger both fluids in the heat exchanger flow in the same direction.

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. Https engineers academy product level 4 higher national certificate hnc in mechanical engineering in this video tutorial you will learn how to calculate. Calculate calculate outlet temperature for hot and cold stream for given flowrates inlet temperature specific heat area of the exchanger and overall heat transfer coefficient u. 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.

Counter parallel flow heat exchanger tube length calculation. The currently calculating value will always be highlighted in green. 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. Lmtd calculation calculate log mean temperature difference lmtd for shell and tube exchanger for counter current and co current flow.

A box will be highlighted yellowif it needs input. Figure 9 represents the directions of fluid flow in the parallel and counter flow exchangers.
