its me again, as said before I am trying to build an ROV for 100 meters
I want to build azimuth propellers, for that i am using a stepper motor with titanium Magnetic coupling, this is great for watertight but here I have a problem
if we go under 100 meters subsea, we have 11 atm of pressure if we go to formula:
p=sea water 1030
g= gravity 9.8
h= 100 meters
P= 1,009,400 Pa
S= my propeller lenght
F=1,009,400Pa * .2meters
F= 201,880 Newtons!!
so the sae is giving 201K newtons force to my building, how much Torque do i need on my stepper motor to move my azimuth propeller?? or am I doing anything wrong here??
please i need help
