Calculos del YEIS

Calculated Volume = ((Hose Diameter (mm)/20)^2*PI() / (((RPM/60) *2*PI() / (Speed Of Sound (meters/second)*100))^2 * (Hose Length (cm)+1.57 * (Hose Diameter (mm)/20))))

Calculated RPM = (((Speed Of Sound (meters/second)*100) / (2*PI())) *Square Root ((PI*(Hose Diameter (mm)/20)^2) / (Volume (cc's) * (Hose Length (cm) + 1.57 * (Hose Diameter (mm)/20))))) * 60

Calculated Hose Length = (((Hose Diameter (mm)/20)^2 * PI()) / (Volume (cc's) * ((2*PI() * RPM / 60 / (Speed Of Sound (meters/second) * 100))^2))) -((Hose Diameter (mm)/20) * 1.57)
