Change in Pressure given Leakage Velocity Solution

Follow our step by step solution on how to calculate Change in Pressure given Leakage Velocity?

FIRST Step Consider the formula

Δp = \frac{8 \cdot d l \cdot μ \cdot v}{{r s}^{2}}

Next Step Substitute values of Variables

∴

Δp = \frac{8 \cdot 1.5mm \cdot 7.8cP \cdot 119.6581m/s}{{10mm}^{2}}

Next Step Convert Units

∴

Δp = \frac{8 \cdot 0.0015m \cdot 0.0078Pa*s \cdot 119.6581m/s}{{0.01m}^{2}}

Next Step Prepare to Evaluate

∴

Δp = \frac{8 \cdot 0.0015 \cdot 0.0078 \cdot 119.6581}{{0.01}^{2}}

Next Step Evaluate

∴

Δp = 111.9999816Pa

Next Step Convert to Output's Unit

∴

Δp = 0.0001119999816MPa

LAST Step Rounding Answer

∴

Δp = 0.0001MPa
