The cavitating flow regimes related to the cavitation number, [sigma] = 0,59, and [sigma] = 0,64 defined the value of the saturation pressure [P.
The cavitating flow regimes related to the cavitation number, [sigma] = 2,4 and [sigma] = 2,44 defined the value of the saturation pressure [P.
When the cavitation number becomes zero, cavitation will begin to occur.
