Evaporation Loss Per Day given Change in Vapour Pressure Solution

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

FIRST Step Consider the formula

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

Next Step Substitute values of Variables

∴

E = 0.75 \cdot (1.465 - (0.00732 \cdot 74.83cmHg)) \cdot (0.44 + (0.0732 \cdot 8km/h)) \cdot 0.2cmHg

Next Step Convert Units

∴

E = 0.75 \cdot (1.465 - (0.00732 \cdot 74.83cmHg)) \cdot (0.44 + (0.0732 \cdot 2.2222m/s)) \cdot 0.2cmHg

Next Step Prepare to Evaluate

∴

E = 0.75 \cdot (1.465 - (0.00732 \cdot 74.83)) \cdot (0.44 + (0.0732 \cdot 2.2222)) \cdot 0.2

Next Step Evaluate

∴

E = 0.0008291889376m

Next Step Convert to Output's Unit

∴

E = 0.08291889376cm

LAST Step Rounding Answer

∴

E = 0.0829cm
