Dry Bulb Temperature given Vapor Density Solution

Follow our step by step solution on how to calculate Dry Bulb Temperature given Vapor Density?

FIRST Step Consider the formula

t d = \frac{ω \cdot (p t - p v)}{287 \cdot ρ v}

Next Step Substitute values of Variables

∴

t d = \frac{0.25 \cdot (189Bar - 60Bar)}{287 \cdot 32kg/m³}

Next Step Convert Units

∴

t d = \frac{0.25 \cdot (1.9E+7Pa - 6E+6Pa)}{287 \cdot 32kg/m³}

Next Step Prepare to Evaluate

∴

t d = \frac{0.25 \cdot (1.9E+7 - 6E+6)}{287 \cdot 32}

Next Step Evaluate

∴

t d = 351.154181184669K

LAST Step Rounding Answer

∴

t d = 351.1542K
