Calculation method

Calculation method

Condensate mass rate (kg/hour)

Latent duty / supplied vaporization enthalpy gives mass rate; no psychrometric state inference.

Condensate mass (kg)

Latent duty / supplied vaporization enthalpy gives mass rate; no psychrometric state inference.

Symbols and units
a
Latent cooling duty (kW)
b
User-supplied latent heat of vaporization (kJ/kg)
c
Operating time (hours)

Use the units shown. A list keeps the order in which you enter its values. The symbol ^ means “raised to the power of”.

Assumptions & limits

Assumptions & limits

  • User-supplied measurements and assumptions; Latent duty / supplied vaporization enthalpy gives mass rate; no psychrometric state inference. Supported limits: Finite numeric values bounded to 1e9 magnitude; lists and tables contain 1–100 records unless a stricter bound is stated. Inputs use the units shown. Lists explicitly paired by a method must have matching lengths; independent polynomial coefficient vectors may differ. Respect stated physical, interpolation, policy and computational domain limits.
