Partial Pressure of Water Vapor given Specific Humidity Solution

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

FIRST Step Consider the formula

p v = \frac{p t}{1 + \frac{0.622}{ω}}

Next Step Substitute values of Variables

∴

p v = \frac{100Bar}{1 + \frac{0.622}{0.25}}

Next Step Convert Units

∴

p v = \frac{1E+7Pa}{1 + \frac{0.622}{0.25}}

Next Step Prepare to Evaluate

∴

p v = \frac{1E+7}{1 + \frac{0.622}{0.25}}

Next Step Evaluate

∴

p v = 2866972.47706422Pa

Next Step Convert to Output's Unit

∴

p v = 28.6697247706422Bar

LAST Step Rounding Answer

∴

p v = 28.6697Bar
