Inlet Pressure in Terms of Pumping Power Solution

STEP 0: Pre-Calculation Summary

Formula Used

Inlet Pressure for Bearing = Outlet Pressure for Bearing+(Pumping Power for Bearing/Flow of lubricant from step bearing)
P_i = P_o+(kW_p/Q_sb)
This formula uses 4 Variables

Variables Used

Inlet Pressure for Bearing - (Measured in Pascal) - The Inlet Pressure for Bearing is defined as the pressure at the inlet or inside the bearing.
Outlet Pressure for Bearing - (Measured in Pascal) - The Outlet Pressure for Bearing is defined as the pressure outside the bearing.
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

Outlet Pressure for Bearing: 1.1 Megapascal --> 1100000 Pascal (Check conversion here)
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_i = P_o+(kW_p/Q_sb) --> 1100000+(1950/0.00048)

Evaluating ... ...

P_i = 5162500

STEP 3: Convert Result to Output's Unit

5162500 Pascal -->5.1625 Megapascal (Check conversion here)

FINAL ANSWER

5.1625 Megapascal <-- Inlet Pressure for Bearing

(Calculation completed in 00.020 seconds)
