The pressure in a submarine inside water(adsbygoogle = window.adsbygoogle || []).push({});

P=h*ρ*g+Pa

Okay,

Since there's Atmospheric pressure inside the submarine (Pa),we calculate the total pressure on the submarine from the relation=h*density*g

we just neglect the atmospheric pressure

why?I don't understand?

Why don't we calculate the total pressure from the relation P=hρg+2Pa?

does the atmospheric pressure in the submarine have a different direction?
