Log Mean Temperature Difference LMTD is an indicator of the average temperature difference between the hot and cold fluids in a heat exchanger.

. The log mean temperature difference LMTD is used to determine the temperature driving force for heat transfer in flow systems. Why LMTD is used. In a heat exchanger which passes two fluids - hot and cold analysis of how much heat is transferred is done by LMTD.

Log Mean Temperature Difference Heat flows between the hot and the cold streams due to temperature difference across the tube acting as a driving force The. LMTD or Log Mean Temperature Difference is an. Log Mean Temperature Difference - Measured in Kelvin - The Log Mean Temperature Difference LMTD is a logarithmic average of the temperature difference between the hot.

The LMTD is a logarithmic average of the temperature. It is calculated using the following. Hot Side Temperature In Temperature.

The log mean temperature difference LMTD is a logarithmic average of the temperature difference in a system and is most often used to model the driving force in heat. The Logarithmic Mean Temperature Difference LMTD is a logarithmic average of the temperature difference between the hot and cold feeds at each end of the heat exchanger. The log mean temperature difference is defined as the logarithmic mean of the temperature difference of the inlet and outlet of the heat exchanger.

Log Mean Temperature Difference LMTD is a logarithmic average of the temperature difference between the hot and cold fluid streams at each end of the heat exchanger. 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. LMTD Calculation Calculate Log Mean Temperature Difference LMTD for shell and tube exchanger for counter-current and co-current flow.

Answer 1 of 3. Log Mean Temperature Difference LMTD As heat is transferred from a one fluid to another fluid in a heat exchanger the temperature of one fluid will begin to rise as it passes through the heat. The log mean temperature difference is The heat transfer rate will be View chapter Purchase book Heat exchangers Charles H.
