Pressure Difference in Terms of Flow of Lubricant Solution

Follow our step by step solution on how to calculate Pressure Difference in Terms of Flow of Lubricant?

FIRST Step Consider the formula

ΔP = l \cdot 12 \cdot μ l \cdot \frac{Q slot}{(h^{3}) \cdot b}

Next Step Substitute values of Variables

∴

ΔP = 48mm \cdot 12 \cdot 220cP \cdot \frac{15mm³/s}{({0.02mm}^{3}) \cdot 49mm}

Next Step Convert Units

∴

ΔP = 0.048m \cdot 12 \cdot 0.22Pa*s \cdot \frac{1.5E-8m³/s}{({2E-5m}^{3}) \cdot 0.049m}

Next Step Prepare to Evaluate

∴

ΔP = 0.048 \cdot 12 \cdot 0.22 \cdot \frac{1.5E-8}{({2E-5}^{3}) \cdot 0.049}

Next Step Evaluate

∴

ΔP = 4848979.59183673Pa

Next Step Convert to Output's Unit

∴

ΔP = 4.84897959183673MPa

LAST Step Rounding Answer

∴

ΔP = 4.849MPa
