Change in Vapour Pressure given Evaporation Loss Per Day Solution

Follow our step by step solution on how to calculate Change in Vapour Pressure given Evaporation Loss Per Day?

FIRST Step Consider the formula

δV = \frac{E}{C' \cdot (1.465 - (0.00732 \cdot P a)) \cdot (0.44 + (0.0732 \cdot u))}

Next Step Substitute values of Variables

∴

δV = \frac{8.29cm}{0.75 \cdot (1.465 - (0.00732 \cdot 74.83cmHg)) \cdot (0.44 + (0.0732 \cdot 8km/h))}

Next Step Convert Units

∴

δV = \frac{0.0829m}{0.75 \cdot (1.465 - (0.00732 \cdot 74.83cmHg)) \cdot (0.44 + (0.0732 \cdot 2.2222m/s))}

Next Step Prepare to Evaluate

∴

δV = \frac{0.0829}{0.75 \cdot (1.465 - (0.00732 \cdot 74.83)) \cdot (0.44 + (0.0732 \cdot 2.2222))}

Next Step Evaluate

∴

δV = 266.58324294557Pa

Next Step Convert to Output's Unit

∴

δV = 0.199954428335586cmHg

LAST Step Rounding Answer

∴

δV = 0.2cmHg
