cavitation Number Vapor Pressure formula

\(\large{ p_v =  p  \;-\;  \frac {Ca \;\rho\; U^2} {2}  }\) 
Symbol English Metric
\(\large{ p_v }\) = vapor pressure \(\large{\frac{lbf}{in^2}}\)   \(\large{Pa}\)
\(\large{ Ca }\) = Cavitation number \(\large{ dimensionless }\)
\(\large{ U }\) = characteristic velocity \(\large{\frac{ft}{sec}}\)  \(\large{\frac{m}{s}}\) 
\(\large{ \rho }\)  (Greek symbol rho) = density of fluid \(\large{\frac{lbm}{ft^3}}\)  \(\large{\frac{kg}{m^3}}\) 
\(\large{ p }\) = pressure \(\large{\frac{lbf}{in^2}}\)   \(\large{Pa}\)
