Evaporation Loss Per Day Solution

Follow our step by step solution on how to calculate Evaporation Loss Per Day?

FIRST Step Consider the formula

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

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 (0.6cmHg - 0.4cmHg)

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 (0.6cmHg - 0.4cmHg)

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 (0.6 - 0.4)

Next Step Evaluate

∴

E = 0.08291889376m

Next Step Convert to Output's Unit

∴

E = 8.291889376cm

LAST Step Rounding Answer

∴

E = 8.2919cm
