Here is how the Specific Humidity given Enthalpy of Moist Air equation looks like.

0.25 = \frac{787.8 - 1.005 \cdot 110}{2500 + 1.9 \cdot 110}

0.25 = \frac{787.8kJ/kg - 1.005 \cdot 110}{2500 + 1.9 \cdot 110}

0.25 = \frac{787.8 - 1.005 \cdot 110}{2500 + 1.9 \cdot 110}

Specific Humidity given Enthalpy of Moist Air Solution

Follow our step by step solution on how to calculate Specific Humidity given Enthalpy of Moist Air?

FIRST Step Consider the formula

ω = \frac{h - 1.005 \cdot t db}{2500 + 1.9 \cdot t db}

Next Step Substitute values of Variables

∴

ω = \frac{787.8kJ/kg - 1.005 \cdot 110}{2500 + 1.9 \cdot 110}

Next Step Prepare to Evaluate

∴

ω = \frac{787.8 - 1.005 \cdot 110}{2500 + 1.9 \cdot 110}

LAST Step Evaluate

∴

ω = 0.25
