Homework Statement
An evacuated spherical diving bell containing a camera is in the ocean at a depth of 121 m. It has a flat, transparent, circular port with a diameter of 19.7 cm. Find the magnitude of the total force on the port (use ρseawater) = 1025 kg/m3).
Homework Equations
P(total)= ρgh+P(atm)
A=[tex]\pi[/tex]R^2
The Attempt at a Solution
I know that you need to find the total pressure on the bell. And then i think you have to subtract that total pressure from atmospheric pressure. this is what i have been doing and it is not working correctly. does anyone have any ideas?
Thanx!
