Question

Lake Baikal in Siberia has a maximum depth of 1642 m. What is the water
pressure at this depth? (Ignore atmospheric pressure - looking for gauge
pressure)

Answer 1

Explanation:

Fluid gauge pressure is:

P = ρgh

where ρ is the fluid density and h is the depth of the fluid.

P = (1000 kg/m³) (9.8 m/s²) (1642 m)

P = 16,091,600 Pa

Rounded to four significant figures, the gauge pressure is 16.09 MPa.
