    Dear all,
    I am doing hand calculation for stress at the base of propeller using cantilever beam method mentioned in Cartlon book. I have an input details required for stress calculation except
    1)Mechanical efficiency , 2) Propeller open water efficiency and 3) Taylor wake fraction.
    The calculation I am doing is for twin skew propeller ship.Anybody has an idea regarding their values.From literature study approximate value for Taylor wake fraction is in range of 0.25-0.30.
    I will be thankful if anybody share the values and refrence.
    Regards,
