Question

What is the absolute pressure at a depth of 9.23 m below the surface of a deep lake? Assume atmospheric pressure is 1.01×10^5 Pa.

science physics

Answer 1

Answer #1

Gravitational acceleration = g = 9.81 m/s²

Density of water = = 1000 kg/m³

Atmospheric pressure = P_atm = 1.01 x 10⁵ Pa

Depth below the surface of the lake = H = 9.23 m

Pressure at this depth = P

P = P_atm + gH

P = 1.01x10⁵ + (1000)(9.81)(9.23)

P = 1.915 x 10⁵ Pa

Absolute pressure at a depth of 9.23 m below the surface of a deep lake = 1.915 x 10⁵ Pa
