Poiseuille's Equation for Compressible Fluids
Poiseuille's Velocity Equation for Compressible Fluids formula |
||
| \( v = ( r^2 \;/\; 16 \; \eta \; l ) \; ( p_1^2 - p_2^2 \;/\; p_1 ) \) | ||
| Symbol | English | Metric |
| \( v \) = velocity of fluid | \(ft\;/\;sec\) | \(m\;/\;s\) |
| \( r \) = radius of tube | \(in\) | \(mm\) |
| \( \eta \) (Greek symbol eta) = viscosity of fluid | \(lbf - sec\;/\;ft^2\) | \(Pa - s \) |
| \( l \) = length of tube | \(ft\) | \(m\) |
| \( p_1 \) = input pressure | \(lbf\;/\;in^2\) | \(Pa\) |
| \( p_2 \) = output pressure | \(lbf\;/\;in^2\) | \(Pa\) |
