Quick LMTD calculator


This is a sample of the Quick LMTD calculator. To access the working calculator, please sign up for free membership trial.

Following calculator can be used to quickly calculate 'Log Mean Temperature Difference' or 'LMTD' for a heat exchanger. This calculator uses the following simple formula to calculate LMTD.

Here is the temperature difference between hot and cold fluids at one end of the heat exchanger and is the temperature difference between hot and cold fluids at the other end of the heat exchanger.

Heat Exchanger Type
Hot fluid inlet T 0C
Hot fluid outlet T 0C
Cold fluid inlet T 0C
Cold fluid outlet T 0C
Log Mean Temperature Difference (LMTD) 0C
