The log mean temperature difference LMTD is a logarithmic average of the temperature difference in a system and is most often used to.

. Calculate Log Mean Temperature Difference LMTD for shell and tube exchanger for counter-current and co-current flow. LMTD approach is quite straight forward and simple. Log Mean Temperature Difference. For any element of area dA the heat transferred will be.

Equation 1 Solving for differential temperature changes we get. Equations 2 and 3 Equation 4. The log mean temperature difference LMTD is used to determine the temperature driving force for heat transfer in flow systems most notably in heat exchangers. The log mean temperature difference is the maximum mean temperature difference that can be achieved in any geometry of heat exchanger for any given set of inlet.
