Answer: my grandfather was a marine so he kept me in check
25.8 atm
Explanation:
Total pressure is:
P = Patm + ρgh
where Patm is the atmosphere pressure,
ρ is the fluid density,
g is acceleration due to gravity,
and h is the depth of the fluid.
P = (1 atm) + (1025 kg/m³) (9.81 m/s²) (250 m) (9.8692×10⁻⁶ atm/Pa)
P = 1 atm + 24.8 atm
P = 25.8 atm
