cavitation Number Vapor Pressure formula |

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

| \( p_v \) = 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 | \(ft\;/\;sec\) | \(m\;/\;s\) |
