1. What is Oil Flow Through Plain Radial Bush Seal?

Oil Flow Through Plain Radial Bush Seal Due To Leakage Under Laminar Flow Condition refers to the amount of oil that leaks through a plain radial bush seal under laminar flow conditions. This calculation is important for designing and analyzing sealing systems in mechanical engineering applications.

2. How Does the Calculator Work?

The calculator uses the formula:

\[ Q = \frac{2\pi a (P_s - \frac{P_e}{10^6})}{a - b} \times q \]

Where:

\( Q \) — Oil Flow From Bush Seal (m³/s)
\( a \) — Outer Radius of Plain Bush Seal (m)
\( P_s \) — Minimum Percentage Compression (%)
\( P_e \) — Exit Pressure (Pa)
\( b \) — Inner Radius of Plain Bush Seal (m)
\( q \) — Volumetric Flow Rate Per Unit Pressure (m³/s)
\( \pi \) — Archimedes' constant (approximately 3.1416)

Explanation: This formula calculates the oil flow through a plain radial bush seal considering the pressure difference, geometric parameters, and flow characteristics under laminar flow conditions.

3. Importance of Oil Flow Calculation

Details: Accurate calculation of oil flow through bush seals is crucial for designing efficient sealing systems, preventing leakage, optimizing lubrication, and ensuring proper functioning of mechanical components in various industrial applications.

4. Using the Calculator

Tips: Enter all values in appropriate units. Outer radius must be greater than inner radius. All values must be positive numbers. The calculator assumes laminar flow conditions and proper seal geometry.
