Atmospheric Pressure given Evaporation Loss Per Day Solution

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

FIRST Step Consider the formula

P a = \frac{1.456 - (\frac{E}{C' \cdot (0.44 + (0.0732 \cdot u)) \cdot (V - v)})}{0.00732}

Next Step Substitute values of Variables

∴

P a = \frac{1.456 - (\frac{8.29cm}{0.75 \cdot (0.44 + (0.0732 \cdot 8km/h)) \cdot (0.6cmHg - 0.4cmHg)})}{0.00732}

Next Step Convert Units

∴

P a = \frac{1.456 - (\frac{0.0829m}{0.75 \cdot (0.44 + (0.0732 \cdot 2.2222m/s)) \cdot (0.6cmHg - 0.4cmHg)})}{0.00732}

Next Step Prepare to Evaluate

∴

P a = \frac{1.456 - (\frac{0.0829}{0.75 \cdot (0.44 + (0.0732 \cdot 2.2222)) \cdot (0.6 - 0.4)})}{0.00732}

Next Step Evaluate

∴

P a = 98163.7139852023Pa

Next Step Convert to Output's Unit

∴

P a = 73.6290439576381cmHg

LAST Step Rounding Answer

∴

P a = 73.629cmHg
