Here is how the Actual Vapour Pressure given Evaporation Loss Per Month equation looks like.

0.4 = 0.6 - (\frac{8.2}{0.36 \cdot (1 + (\frac{8}{16}))})

0.4cmHg = 0.6cmHg - (\frac{8.2cm}{0.36 \cdot (1 + (\frac{8km/h}{16}))})

0.4 = 0.6 - (\frac{8.2}{0.36 \cdot (1 + (\frac{8}{16}))})

Actual Vapour Pressure given Evaporation Loss Per Month Solution

Follow our step by step solution on how to calculate Actual Vapour Pressure given Evaporation Loss Per Month?

FIRST Step Consider the formula

v = V - (\frac{E m}{C \cdot (1 + (\frac{u}{16}))})

Next Step Substitute values of Variables

∴

v = 0.6cmHg - (\frac{8.2cm}{0.36 \cdot (1 + (\frac{8km/h}{16}))})

Next Step Convert Units

∴

v = 0.6cmHg - (\frac{0.082m}{0.36 \cdot (1 + (\frac{2.2222m/s}{16}))})

Next Step Prepare to Evaluate

∴

v = 0.6 - (\frac{0.082}{0.36 \cdot (1 + (\frac{2.2222}{16}))})

Next Step Evaluate

∴

v = 533.288Pa

LAST Step Convert to Output's Unit

∴

v = 0.4cmHg
