Partial Pressure of Dry Air given Specific Humidity Solution

Follow our step by step solution on how to calculate Partial Pressure of Dry Air given Specific Humidity?

FIRST Step Consider the formula

p a = \frac{0.622 \cdot p v}{ω}

Next Step Substitute values of Variables

∴

p a = \frac{0.622 \cdot 28.6697Bar}{0.25}

Next Step Convert Units

∴

p a = \frac{0.622 \cdot 2.9E+6Pa}{0.25}

Next Step Prepare to Evaluate

∴

p a = \frac{0.622 \cdot 2.9E+6}{0.25}

Next Step Evaluate

∴

p a = 7133026.336Pa

Next Step Convert to Output's Unit

∴

p a = 71.33026336Bar

LAST Step Rounding Answer

∴

p a = 71.3303Bar
