Change in Pressure given Leakage Velocity Solution

STEP 0: Pre-Calculation Summary

Formula Used

Pressure Change = (Velocity*8*(Incremental Length in Direction of Velocity)*Absolute Viscosity of Oil in Seals)/((Radius of Seal)^2)
dp = (v*8*(dl)*μ)/((r_seal)^2)
This formula uses 5 Variables

Variables Used

Pressure Change - (Measured in Pascal) - Pressure Change is defined as the difference between final pressure and initial pressure. In differential form, it is represented as dP.
Velocity - (Measured in Meter per Second) - Velocity is a vector quantity (it has both magnitude and direction) and is the rate of change of the position of an object with respect to time.
Incremental Length in Direction of Velocity - (Measured in Meter) - Incremental Length in Direction of Velocity is defined as a length increase in velocity direction.
Absolute Viscosity of Oil in Seals - (Measured in Pascal Second) - The Absolute Viscosity of Oil in Seals represents the ratio of a fluid's shear stress to its velocity gradient. It is a fluid's internal flow resistance.
Radius of Seal - (Measured in Meter) - Radius of Seal is a radial line from the focus to any point of a curve.

STEP 1: Convert Input(s) to Base Unit

Velocity: 60 Meter per Second --> 60 Meter per Second No Conversion Required
Incremental Length in Direction of Velocity: 1.5 Millimeter --> 0.0015 Meter (Check conversion here)
Absolute Viscosity of Oil in Seals: 7.8 Centipoise --> 0.0078 Pascal Second (Check conversion here)
Radius of Seal: 10 Millimeter --> 0.01 Meter (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

dp = (v*8*(dl)*μ)/((r_seal)^2) --> (60*8*(0.0015)*0.0078)/((0.01)^2)

Evaluating ... ...

dp = 56.16

STEP 3: Convert Result to Output's Unit

56.16 Pascal -->5.616E-05 Megapascal (Check conversion here)

FINAL ANSWER

5.616E-05 ≈ 5.6E-5 Megapascal <-- Pressure Change
