Here is how the Dry Bulb Temperature given Enthalpy of Moist Air equation looks like.

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

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

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

Dry Bulb Temperature given Enthalpy of Moist Air Solution

Follow our step by step solution on how to calculate Dry Bulb Temperature given Enthalpy of Moist Air?

FIRST Step Consider the formula

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

Next Step Substitute values of Variables

∴

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

Next Step Prepare to Evaluate

∴

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

LAST Step Evaluate

∴

t db = 110
