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.
