[PSUBS-MAILIST] need information about how to choose a submarine propeller

[ayman farhat <ayman_17ph2004@yahoo.com>]

after i did many researches on how to choose a submarine propeller and i knew that the propeller's diameter is 0.4 the total diameter of the external hull of the submarine (which is to have a cylindrical shape ) however i knew later that  the motor's rotation per minute and horse power  also influences the propeller's diameter to be chosen.

i need to check the validity of these information, especially regarding the influence of the motor's rotation per minute and horse power on the propeller's diameter.

i would be greatfull for your help.
