LMTD Calculator

The log mean temperature difference or, in short, LMTD, can determine the driving force for heat transfer systems. As its name suggests, this parameter is calculated as the logarithmic average of the differences in temperatures for both the hot and the cold streams at each end of the heat exchanger.
The LMTD Calculator provides users with a simple way to determine the LMTD. In a simple window where the required input is filled in by you, this calculator can display the temperature deriving force for the counter current flow and the co-current flow.
The main window is straightforward and there are not many options available. You are required to enter the temperature values for the hot sides and the cold sides for both the inlet and the outlet. By default, these values use the Celsius scale a measurement unit, but you can also change this setting from the designated menu. The other available options are Kelvin and Fahrenheit.
Once all the values are provided, all that is left for you to do is hit the “Calculate” button and the application does all the computing. The temperature deriving force for the counter current flow and the co current flow are displayed almost instantly.
