Excel calculator for LMTD

LMTD, Log mean temperature difference is the temperature driving force for heat transfer in flow systems. When you are calculating heat transfer by overall heat transfer coefficient (U), you should not simply multiply temperature difference of hot stream or cold stream. Multiplying this temperature difference doesn't account the overall driving force.
