U-Tube Manometer equation Solution

Follow our step by step solution on how to calculate U-Tube Manometer equation?

FIRST Step Consider the formula

P a = (γ m \cdot h m) - (γ 1 \cdot h 1)

Next Step Substitute values of Variables

∴

P a = (500N/m³ \cdot 75mm) - (1342N/m³ \cdot 122mm)

Next Step Convert Units

∴

P a = (500N/m³ \cdot 0.075m) - (1342N/m³ \cdot 0.122m)

Next Step Prepare to Evaluate

∴

P a = (500 \cdot 0.075) - (1342 \cdot 0.122)

LAST Step Evaluate

∴

P a = -126.224Pa
