Enthalpy of Moist Air Solution

STEP 0: Pre-Calculation Summary

Formula Used

Enthalpy of Moist Air = 1.005*Dry Bulb Temperature in °C+Specific Humidity*(2500+1.9*Dry Bulb Temperature in °C)
h = 1.005*t_db+ω*(2500+1.9*t_db)
This formula uses 3 Variables

Variables Used

Enthalpy of Moist Air - (Measured in Kilojoule per Kilogram) - The Enthalpy of Moist Air is the sum of the enthalpy of the dry air and the enthalpy of the water vapour.
Dry Bulb Temperature in °C - Dry bulb temperature in °C is the temperature of air measured by a thermometer freely exposed to the air but shielded from radiation and moisture.
Specific Humidity - Specific Humidity is the ratio of the mass of water vapor to the total mass of the air parcel.

STEP 1: Convert Input(s) to Base Unit

Dry Bulb Temperature in °C: 110 --> No Conversion Required
Specific Humidity: 0.25 --> No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

h = 1.005*t_db+ω*(2500+1.9*t_db) --> 1.005*110+0.25*(2500+1.9*110)

Evaluating ... ...

h = 787.8

STEP 3: Convert Result to Output's Unit

787800 Joule per Kilogram -->787.8 Kilojoule per Kilogram (Check conversion here)

FINAL ANSWER

787.8 Kilojoule per Kilogram <-- Enthalpy of Moist Air

(Calculation completed in 00.004 seconds)

Enthalpy of Moist Air Formula

Enthalpy of Moist Air = 1.005*Dry Bulb Temperature in °C+Specific Humidity*(2500+1.9*Dry Bulb Temperature in °C)
h = 1.005*t_db+ω*(2500+1.9*t_db)

What is dry-bulb temperature?

The Dry Bulb Temperature refers basically to the ambient air temperature. It is called "Dry Bulb" because the air temperature is indicated by a thermometer not affected by the moisture of the air. When people refer to the temperature of the air they are normally referring to the dry bulb temperature.
