STEP 1: Convert Input(s) to Base Unit

Outer Radius of Plain Bush Seal: 15 Millimeter --> 0.015 Meter (Check conversion here)
Minimum Percentage Compression: 16 --> No Conversion Required
Exit Pressure: 2.1 Megapascal --> 2100000 Pascal (Check conversion here)
Inner Radius of Plain Bush Seal: 4.2 Millimeter --> 0.0042 Meter (Check conversion here)
Volumetric Flow Rate Per Unit Pressure: 7.788521 Cubic Millimeter per Second --> 7.788521E-09 Cubic Meter per Second (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

Q = (2*pi*a*(P_s-P_e/10^6))/(a-b)*q --> (2*pi*0.015*(16-2100000/10^6))/(0.015-0.0042)*7.788521E-09

Evaluating ... ...

Q = 9.44750580409513E-07

STEP 3: Convert Result to Output's Unit

9.44750580409513E-07 Cubic Meter per Second -->944.750580409513 Cubic Millimeter per Second (Check conversion here)

FINAL ANSWER

944.750580409513 ≈ 944.7506 Cubic Millimeter per Second <-- Oil Flow From Bush Seal
