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 |
