Differential Pressure between Two Points Solution

Follow our step by step solution on how to calculate Differential Pressure between Two Points?

FIRST Step Consider the formula

Δp = γ 1 \cdot h 1 - γ 2 \cdot h 2

Next Step Substitute values of Variables

∴

Δp = 1342N/m³ \cdot 12cm - 1223N/m³ \cdot 7.8cm

Next Step Convert Units

∴

Δp = 1342N/m³ \cdot 0.12m - 1223N/m³ \cdot 0.078m

Next Step Prepare to Evaluate

∴

Δp = 1342 \cdot 0.12 - 1223 \cdot 0.078

LAST Step Evaluate

∴

Δp = 65.646Pa
