How to Calculate Log Mean Temperature Difference for Counter Current Flow?
Log Mean Temperature Difference for Counter Current Flow calculator uses Log Mean Temperature Difference = ((Outlet Temperature of Hot Fluid-Inlet Temperature of Cold Fluid)-(Inlet Temperature of Hot Fluid-Outlet Temperature of Cold Fluid))/ln((Outlet Temperature of Hot Fluid-Inlet Temperature of Cold Fluid)/(Inlet Temperature of Hot Fluid-Outlet Temperature of Cold Fluid)) to calculate the Log Mean Temperature Difference, The Log Mean Temperature Difference for Counter Current Flow in is used to determine the temperature driving force for heat transfer in flow systems, most notably in heat exchangers. The LMTD is a logarithmic average of the temperature difference between the hot and cold streams at each end of the exchanger. Log Mean Temperature Difference is denoted by LMTD symbol.
How to calculate Log Mean Temperature Difference for Counter Current Flow using this online calculator? To use this online calculator for Log Mean Temperature Difference for Counter Current Flow, enter Outlet Temperature of Hot Fluid (T_{ho}), Inlet Temperature of Cold Fluid (T_{ci}), Inlet Temperature of Hot Fluid (T_{hi}) & Outlet Temperature of Cold Fluid (T_{co}) and hit the calculate button. Here is how the Log Mean Temperature Difference for Counter Current Flow calculation can be explained with given input values -> 19.57615 = ((20-5)-(35-10))/ln((20-5)/(35-10)).
