Leakage of Fluid past Rod Solution

Follow our step by step solution on how to calculate Leakage of Fluid past Rod?

FIRST Step Consider the formula

Q l = \frac{π \cdot c^{3}}{12} \cdot (p 1 - p 2) \cdot \frac{d}{l \cdot μ}

Next Step Substitute values of Variables

∴

Q l = \frac{π \cdot {0.9mm}^{3}}{12} \cdot (200.8501MPa - 2.85MPa) \cdot \frac{12.6mm}{0.0383mm \cdot 7.8cP}

Next Step Substitute values of Constants

∴

Q l = \frac{3.1416 \cdot {0.9mm}^{3}}{12} \cdot (200.8501MPa - 2.85MPa) \cdot \frac{12.6mm}{0.0383mm \cdot 7.8cP}

Next Step Convert Units

∴

Q l = \frac{3.1416 \cdot {0.0009m}^{3}}{12} \cdot (2E+8Pa - 2.9E+6Pa) \cdot \frac{0.0126m}{3.8E-5m \cdot 0.0078Pa*s}

Next Step Prepare to Evaluate

∴

Q l = \frac{3.1416 \cdot {0.0009}^{3}}{12} \cdot (2E+8 - 2.9E+6) \cdot \frac{0.0126}{3.8E-5 \cdot 0.0078}

Next Step Evaluate

∴

Q l = 1595.40092539391m³/s

Next Step Convert to Output's Unit

∴

Q l = 1595400925393.91mm³/s

LAST Step Rounding Answer

∴

Q l = 1.6E+12mm³/s

How to Evaluate Leakage of Fluid past Rod?

Leakage of Fluid past Rod evaluator uses Fluid Leakage From Packingless Seals = (pi*Radial Clearance For Seals^3)/12*(Fluid Pressure 1 For Seal-Fluid Pressure 2 For Seal)*Diameter of Seal Bolt/(Depth of U Collar*Absolute Viscosity of Oil in Seals) to evaluate the Fluid Leakage From Packingless Seals, Leakage of Fluid past Rod typically refers to the fluid that escapes around a cylindrical rod in a mechanical system, such as a piston or a valve stem, often due to an imperfect seal. The flow rate of the leakage can be influenced by factors such as the pressure difference, the viscosity of the fluid, and the dimensions of the gap between the rod and the surrounding cylinder. Fluid Leakage From Packingless Seals is denoted by Q_l symbol.
