Using P0 = 101,325 Pa, ρ = 1000 kg/m^3, g = 9.8 m/s^2, h = 10 m, what is the total pressure at depth 10 m in water?

Explanation:
Pressure at depth combines the atmospheric pressure at the surface with the weight of the water column above you. Use P = P0 + ρgh. Hydrostatic part: ρgh = 1000 × 9.8 × 10 = 98,000 Pa. Add the surface pressure: 101,325 + 98,000 = 199,325 Pa. So the total pressure at 10 m depth is 199,325 Pa (about 199 kPa).

Pressure at depth combines the atmospheric pressure at the surface with the weight of the water column above you. Use P = P0 + ρgh.

Hydrostatic part: ρgh = 1000 × 9.8 × 10 = 98,000 Pa.

Add the surface pressure: 101,325 + 98,000 = 199,325 Pa.

So the total pressure at 10 m depth is 199,325 Pa (about 199 kPa).
