    4 Number of calculations

    D = \frac{A - B}{2}
    E = \sqrt{(\pi \cdot A)^2 + C^2}
    F = \sqrt{(\pi \cdot B)^2 + C^2}
    G = \frac{F \cdot D}{E - F}


    • D = Overall Radius
    • A = Outside Flight Diameter
    • B = Inside Flight Diameter
    • C = Pitch of Flight
    • E = Developed Outside Diameter
    • F = Developed Inside Diameter
    • G = Cylindrical Screw Flights
