Pressure at Any Point in Liquids Solution

Follow our step by step solution on how to calculate Pressure at Any Point in Liquids?

FIRST Step Consider the formula

P ab,H = P atm + y \cdot h \cdot (1 + \frac{α v}{[g]})

Next Step Substitute values of Variables

∴

P ab,H = 101325Pa + 9.81kN/m³ \cdot 20000mm \cdot (1 + \frac{10.03m/s²}{[g]})

Next Step Substitute values of Constants

∴

P ab,H = 101325Pa + 9.81kN/m³ \cdot 20000mm \cdot (1 + \frac{10.03m/s²}{9.8066m/s²})

Next Step Convert Units

∴

P ab,H = 101325Pa + 9810N/m³ \cdot 20m \cdot (1 + \frac{10.03m/s²}{9.8066m/s²})

Next Step Prepare to Evaluate

∴

P ab,H = 101325 + 9810 \cdot 20 \cdot (1 + \frac{10.03}{9.8066})

Next Step Evaluate

∴

P ab,H = 498193.525949228Pa

LAST Step Rounding Answer

∴

P ab,H = 498193.5259Pa
