Heat Duty (Q) Calc
Determine the required thermal load for process heating or cooling: sensible heat (m·Cp·ΔT) and optional latent heat (m·L). Metric and US units supported.
What You'll Get
✔ Heat duty in kW, kJ/h, kcal/h, Btu/h
✔ Optional TR (Tons of Refrigeration)
✔ Auto mass flow from ρ & volumetric flow
✔ Sensible + Latent contributions
Process Inputs
or derive from Qv & ρ below
Water ≈ 4.186 kJ/kg·K
same
Unit follows inlet
Use if condensation/evaporation occurs
If set with ρ, overrides Mass Flow
kg/m³
Formulas:
Sensible: Qs = m · Cp · ΔT
Latent: Ql = m · L
Total: Q = Qs + Ql
