The root mean square error (RMSE) was calculated according to the following equation; where n is the number of observations, yi represents the measured values, and ŷi the predicted values.
In fluid dynamics, the dimensionless cavitation number (Ca) is used to predict cavitation Eq. (2). The equation relates the local static pressure in a liquid (p) to the vapor pressure of the liquid (pv), the density (ρ), and the flow velocity (v). Below 0.2 cavitation can be expected.
