This formula uses 5 Variables

Variables Used

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.
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.

STEP 1: Convert Input(s) to Base Unit

Temperature Rise Variable: 21 --> No Conversion Required
Unit bearing pressure for bearing: 0.96 Megapascal --> 960000 Pascal (Check conversion here)
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)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

Δt_r = TRV*p/(ρ*C_p) --> 21*960000/(880*1760)

Evaluating ... ...

Δt_r = 13.0165289256198

STEP 3: Convert Result to Output's Unit

13.0165289256198 Kelvin -->13.0165289256198 Degree Celsius (Check conversion here)

FINAL ANSWER

13.0165289256198 ≈ 13.01653 Degree Celsius <-- Temperature rise of bearing lubricant
