Power Loss or Consumption due to Leakage of Fluid through Face Seal Solution

Follow our step by step solution on how to calculate Power Loss or Consumption due to Leakage of Fluid through Face Seal?

FIRST Step Consider the formula

P l = \frac{π \cdot ν \cdot w^{2}}{13200 \cdot t} \cdot ({r 2}^{4} - {r 1}^{4})

Next Step Substitute values of Variables

∴

P l = \frac{π \cdot 7.25St \cdot {8.5mm}^{2}}{13200 \cdot 1.92mm} \cdot ({20mm}^{4} - {14mm}^{4})

Next Step Substitute values of Constants

∴

P l = \frac{3.1416 \cdot 7.25St \cdot {8.5mm}^{2}}{13200 \cdot 1.92mm} \cdot ({20mm}^{4} - {14mm}^{4})

Next Step Convert Units

∴

P l = \frac{3.1416 \cdot 0.0007m²/s \cdot {0.0085m}^{2}}{13200 \cdot 0.0019m} \cdot ({0.02m}^{4} - {0.014m}^{4})

Next Step Prepare to Evaluate

∴

P l = \frac{3.1416 \cdot 0.0007 \cdot {0.0085}^{2}}{13200 \cdot 0.0019} \cdot ({0.02}^{4} - {0.014}^{4})

Next Step Evaluate

∴

P l = 7.89454306099922E-16W

LAST Step Rounding Answer

∴

P l = 7.9E-16W
