Calculate process heat duty for sensible, latent, and combined phase change loads, per GPSA.
Understand conduction/convection/radiation, LMTD, and heat exchanger design
It computes process heat duty (BTU/hr): sensible heating or cooling (Q = m·Cp·ΔT), latent vaporization or condensation (Q = m·λ), and combined loads that include liquid heat-up, vaporization, and vapor superheat. It uses a temperature-corrected gas Cp and the Watson correlation for latent heat.
No — this tool computes the heat duty only. To size exchanger area from Q = U·A·LMTD (overall coefficient, LMTD, F-correction), use the heat exchanger sizing calculator; the duty computed here is the Q input to that step.
