Question

Calculate the absolute pressure at the bottom of a fresh-water lake at a depth of 31.6 m. Assume the density of the water is 1.00 ✕ 10³ kg/m³ and the air above is at a pressure of 101.3 kPa.

(b) What force is exerted by the water on the window of an underwater vehicle at this depth if the window is circular and has a diameter of 32.0 cm?

Expert Solution

Step 1

Given data:

Depth (d) = 31.6 m

Density of water (ρ) = 1.00×10³ kg/m³

Atmospheric pressure (P_atm) = 101.3 kPa

Diameter of circular window (d) = 32.0 cm = 0.320 m

Required:

The absolute pressure at the bottom of the fresh water and force exerted on the window
