LMTD

(ΔT1 − ΔT2) / ln(ΔT1/ΔT2) with parallel ΔT guard.

Use any consistent temperature unit; LMTD carries the same unit.

ΔT1 = T_hi − T_co ≈ 80.000

ΔT2 = T_ho − T_ci ≈ 35.000

LMTD ≈ 54.4347

Log Mean Temperature Difference (LMTD) helps you (δt1 − δt2) / ln(δt1/δt2) with parallel δt guard. It is commonly used by domain specialists, operations teams, learners for lmtd, log mean temperature difference, heat exchanger.
