Heat-exchanger temperature-difference and insulated-pipe heat-loss tools for fast thermal design screening.
When to use these calculators
Use these calculators for exchanger feasibility checks, thermal-duty estimates, and insulation heat-loss screening.
Typical workflow
Estimate the exchanger driving force with LMTD and correction factor checks.
Estimate pipe heat loss when ambient exposure or insulation thickness matters.
Use the result as a screening value before detailed exchanger or insulation design.
Calculators
Heat Exchanger LMTD Calculator — Log-mean temperature difference for a two-stream exchanger, plus duty Q if you supply U and area.
Heat Exchanger Duty & Area Calculator — Sensible heat duty from flow, specific heat, and temperature change — plus the required exchanger area from U and the LMTD.
Insulated Pipe Heat Loss Calculator — Heat loss per metre and total from an insulated pipe, with the outer-surface temperature (personnel-protection check).
