Chemical Engineering
LMTD Heat Exchanger Calculator
Compute the log mean temperature difference (LMTD) — the effective driving force for heat transfer in a heat exchanger, given the four end-of-fluid temperatures. The standard input to the design equation Q = U·A·LMTD for sizing or rating exchangers.
