INPUT

Inlet Temperature(T_hot-In)

Outlet Temperature(T_hot-Out)

Inlet Temperature(T_cold-In)

Outlet Temperature(T_cold-Out)

OUTPUT

Ensure all input temperatures are in same unit.

LMTD Formula:

 LMTD = (ΔT1 - ΔT2) / ln(ΔT1/ΔT2)

Counter-current Flow

 (ΔT1) = (T_hot-In -T_cold-Out)

 (ΔT2) = (T_hot-Out -T_cold-In)

Counter-current Flow

 (ΔT1) = (T_hot-In -T_cold-In)

 (ΔT2) = (T_hot-Out -T_cold-Out)
