Cavitation Number Vapor Pressure
cavitation Number Vapor Pressure formula |

|
\( p_v = p - ( Ca \; \rho \; U^2 \;/\; 2 )\) (Cavitation Number Vapor Pressure) \( p = Ca \; \rho \; U^2 \;/\; 2 \; ( 1 - \frac{U}{2} ) \) \( Ca = - 2 \; p + 2 \; p_v \;/\; \rho \; U^2 \) \( \rho = 2 \; \left( p - p_v \right) \;/\; Ca \; U^2 \) \( U = \sqrt{ 2\; \left( p - p_v \right) \;/\; Ca \; \rho } \) |

| \( p_v \) = vapor pressure | \(lbf\;/\;in^2\) | \(Pa\) |
| \( p \) = pressure | \(lbf\;/\;in^2\) | \(Pa\) |
| \( Ca \) = Cavitation number | \( dimensionless \) | \( dimensionless \) |
| \( \rho \) (Greek symbol rho) = fluid density | \(lbm\;/\;ft^3\) | \(kg\;/\;m^3\) |
| \( U \) = characteristic velocity | \(ft\;/\;sec\) | \(m\;/\;s\) |
