Unit Bearing Pressure in Terms of Temperature Rise Variable Solution

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

FIRST Step Consider the formula

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

Next Step Substitute values of Variables

∴

p = 0.88g/cm³ \cdot 1.76kJ/kg*°C \cdot \frac{13.2°C}{21}

Next Step Convert Units

∴

p = 880kg/m³ \cdot 1760J/(kg*K) \cdot \frac{13.2K}{21}

Next Step Prepare to Evaluate

∴

p = 880 \cdot 1760 \cdot \frac{13.2}{21}

Next Step Evaluate

∴

p = 973531.428571429Pa

Next Step Convert to Output's Unit

∴

p = 0.973531428571428MPa

LAST Step Rounding Answer

∴

p = 0.9735MPa
