Pressure of Lubricating Oil in Terms Pumping Power Solution

STEP 0: Pre-Calculation Summary

Formula Used

Pressure of Lubricating Oil = Pumping Power for Bearing/Flow of lubricant from step bearing
p_r = kW_p/Q_sb
This formula uses 3 Variables

Variables Used

Pressure of Lubricating Oil - (Measured in Pascal) - The Pressure of Lubricating Oil is the Value of pressure exerted by the lubricating oil.
Pumping Power for Bearing - (Measured in Watt) - The Pumping Power for Bearing is defined as the product of the flow of lubricant and the difference between inlet and outlet pressure.
Flow of lubricant from step bearing - (Measured in Cubic Meter per Second) - Flow of lubricant from step bearing can be defined as the amount of lubricant flowing per unit time between two moving surfaces to reduce the friction between them.

STEP 1: Convert Input(s) to Base Unit

Pumping Power for Bearing: 1.95 Kilowatt --> 1950 Watt (Check conversion here)
Flow of lubricant from step bearing: 480000 Cubic Millimeter per Second --> 0.00048 Cubic Meter per Second (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

p_r = kW_p/Q_sb --> 1950/0.00048

Evaluating ... ...

p_r = 4062500

STEP 3: Convert Result to Output's Unit

4062500 Pascal -->4.0625 Megapascal (Check conversion here)

FINAL ANSWER

4.0625 Megapascal <-- Pressure of Lubricating Oil

(Calculation completed in 00.004 seconds)
