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.
Chemical Engineering
Compressibility Factor Calculator
Estimate the compressibility factor Z of a real gas using reduced pressure, reduced temperature, and the acentric factor. Use this when modeling non-ideal gas behavior in process simulation or equation-of-state calculations.
