    Hi
    I'm trying to design a submarine that is powered by a person but when trying to design the propellers I'm stuck at the wake fraction. How can I calculate this fraction? and is there a value or range of values that I could assume since I really don't have a lot of ways of making tests and examinations.
    Thanks a lot
