Unit Bearing Pressure in Terms of Temperature Rise Variable Solution

STEP 0: Pre-Calculation Summary

Formula Used

Unit bearing pressure for bearing = Density of Lubricating Oil*Specific heat of bearing oil*Temperature rise of bearing lubricant/Temperature Rise Variable
p = ρ*C_p*Δt_r/TRV
This formula uses 5 Variables

Variables Used

Unit bearing pressure for bearing - (Measured in Pascal) - Unit bearing pressure for bearing is the average pressure acting on the contact surface of the bearing.
Density of Lubricating Oil - (Measured in Kilogram per Cubic Meter) - The Density of Lubricating Oil is defined as the mass of a unit volume of oil.
Specific heat of bearing oil - (Measured in Joule per Kilogram per K) - Specific heat of bearing oil is the amount of heat per unit mass required to raise the temperature of the oil by one degree Celsius.
Temperature rise of bearing lubricant - (Measured in Kelvin) - Temperature rise of bearing lubricant is defined as the increase in the temperature of the lubricant as the bearing or the component rotates.
Temperature Rise Variable - The Temperature Rise Variable is defined as the ratio of the product of density, specific, and rise in temperature to unit bearing pressure.

STEP 1: Convert Input(s) to Base Unit

Density of Lubricating Oil: 0.88 Gram per Cubic Centimeter --> 880 Kilogram per Cubic Meter (Check conversion here)
Specific heat of bearing oil: 1.76 Kilojoule per Kilogram per Celcius --> 1760 Joule per Kilogram per K (Check conversion here)
Temperature rise of bearing lubricant: 13.2 Degree Celsius --> 13.2 Kelvin (Check conversion here)
Temperature Rise Variable: 21 --> No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

p = ρ*C_p*Δt_r/TRV --> 880*1760*13.2/21

Evaluating ... ...

p = 973531.428571429

STEP 3: Convert Result to Output's Unit

973531.428571429 Pascal -->0.973531428571428 Megapascal (Check conversion here)

FINAL ANSWER

0.973531428571428 ≈ 0.973531 Megapascal <-- Unit bearing pressure for bearing
