Coefficient of 0.07 (Inlet Value) (The value of the 



total pressure coefficient is about 0.05. The 



inducer consists of four cambered blades 



having a tip inlet angle of 7 degrees 



followed by 12 more heavily loaded 



tandem blades. The real part of 



the coefficients are shown solid 



and the imaginary dotted. Two 



sets of data are shown, fully 



wetted and for a cavitation
