Cavitation Number
Cavitation number is proportional to { (excess of local static head over vapor pressure head) / (velocity head) } and is used in momentum transfer in general and throttling calculations in particular. It is normally defined in the following form :
Where: | ||
gc | = | Dimensional constant |
p | = | Local static pressure |
p_v | = | Vapor pressure |
rho | = | Density |
V | = | Velocity |
