Temperature Rise of Lubricant in Terms of Temperature Rise Variable Solution

Follow our step by step solution on how to calculate Temperature Rise of Lubricant in Terms of Temperature Rise Variable?

FIRST Step Consider the formula

Δt r = TRV \cdot \frac{p}{ρ \cdot C p}

Next Step Substitute values of Variables

∴

Δt r = 21 \cdot \frac{0.96MPa}{0.88g/cm³ \cdot 1.76kJ/kg*°C}

Next Step Convert Units

∴

Δt r = 21 \cdot \frac{960000Pa}{880kg/m³ \cdot 1760J/(kg*K)}

Next Step Prepare to Evaluate

∴

Δt r = 21 \cdot \frac{960000}{880 \cdot 1760}

Next Step Evaluate

∴

Δt r = 13.0165289256198K

Next Step Convert to Output's Unit

∴

Δt r = 13.0165289256198°C

LAST Step Rounding Answer

∴

Δt r = 13.0165°C
