A submarine reaches the depth of 105 m (density of sea water = 1030 kg/m^3).
• Calculate the absolute pressure that the submarine need to be able to withstand.

The absolute pressure that the submarine need to be able to withstand is:
$p= p_{at}+ρgh $=
=$1,01×10^5+1030×9,8066×105 ≅ 1161583,8~Pa ≅ 1,16×10^6~Pa$.

@gramor 👍👌👍
@remanzini_rinaldo - Grazie mille, buona serata.
abs pressure = atmospheric pressure+hydrostatic pressure
p abs = (1,01*10^5 +1030*105*9,806) = 1,16*10^6 Pa
Comment : this is a silly question ; Subs have an inner pressure equal to the atmospheric pressure, as i have personally experienced several times
