    hi,

    wondering if someone could help with determining the cavitation number of a propeller please. It's been a while since I've done this so I'm a bit rusty!
    vessel will be running in the seychelles and Va is 35kts.
    If someone does reply, if you could put your workings I would appreciate it to hopefully remind myself how it's done!

    Thanks

    Fine; just beware of which velocity you are referring to, and for what purpose. Only the cavitation number based on blade leading edge relative inflow velocity has a stringent physical meaning.
