Country-neutral calculator for Heat Esanjoru Preliminary Sizing Analysis - Hydraulic Yag Sogutucu LMTD. For positive terminal hot-to-cold temperature differences: ΔTlm = (ΔT1 − ΔT2)/ln(ΔT1/ΔT2). Equal terminal differences give that same ΔT; near-equal values use a numerically stable limiting approximation. Both terminal temperature differences must be strictly positive and paired consistently with flow direction. Temperature crossing and zero approach are not covered by this simple one-direction model; crossflow and multipass geometries can require correction factor F.
Use consistent units and the requested inputs.
Use the main result and breakdowns as a planning estimate.
For regulated topics, verify current local rules before acting.
For positive terminal hot-to-cold temperature differences: ΔTlm = (ΔT1 − ΔT2)/ln(ΔT1/ΔT2). Equal terminal differences give that same ΔT; near-equal values use a numerically stable limiting approximation.
With ΔT1 = 40 K and ΔT2 = 18 K, LMTD ≈ 27.5514 K.
This is an idealized thermal sizing estimate. Interpret the units and physical direction correctly.
