Pressure Difference between Two Points in Liquid Solution

Follow our step by step solution on how to calculate Pressure Difference between Two Points in Liquid?

FIRST Step Consider the formula

ΔP = S \cdot (D - D 2)

Next Step Substitute values of Variables

∴

ΔP = 0.75kN/m³ \cdot (16m - 15m)

Next Step Convert Units

∴

ΔP = 750N/m³ \cdot (16m - 15m)

Next Step Prepare to Evaluate

∴

ΔP = 750 \cdot (16 - 15)

Next Step Evaluate

∴

ΔP = 750Pa

LAST Step Convert to Output's Unit

∴

ΔP = 750N/m²

How to Evaluate Pressure Difference between Two Points in Liquid?

Pressure Difference between Two Points in Liquid evaluator uses Pressure Difference = Specific Weight of Liquid in Piezometer*(Depth of Point 1-Depth of Point 2) to evaluate the Pressure Difference, The Pressure Difference between Two Points in Liquid formula is defined as a function of specific weight of liquid, and the depth of two points below the free surface in a static mass of liquid. Thus it may be stated that the difference in pressure at any two points in a static mass of liquid varies directly as the difference in depth of the two points. Pressure Difference is denoted by ΔP symbol.
