Moist-Air Enthalpy

h = 1.006 T + W (2501 + 1.86 T) kJ/kg with T in °C, per kg dry air. Approximate, not a certified property.

Thermal & HVAC

h = 1.006 T + W (2501 + 1.86 T) kJ/kg with T in °C, per kg dry air. Approximate, not a certified property.

App id: THERM-13. Reference version 1.0.

How to fill it

Fill the inputs. The tool shows the outputs.

On the tool screen, Calc is the working sheet. Presets stores values you reuse. Reference is the formula, assumptions, and provenance below.

Formula

h = cp,da T + W (h_fg,0 + cp,v T)

Inputs

Name	Unit
Dry-bulb temperature	`C`
Humidity ratio	`kg/kg`

Outputs

Name	Unit
Specific enthalpy (hero result)	`kJ/kg`

Diagnose

This tool does not attach diagnose observations.

Assumptions

Not for metering or certification.

Provenance

Reference roughly 0 °C dry air. cp,da = 1.006 kJ/kg·K, h_fg,0 = 2501 kJ/kg, cp,v = 1.86 kJ/kg·K.
