Question
3. The transparent "biospheres" beneath the Bay of Noli, in Savona, Italy, are part of the three-year-old Nemo's Garden project, which aims to find innovative ways of growing crops in places that lack freshwater or fertile soil (Fig 1). Resembling large balloons, the air-filled structures are anchored to the sea floor and float between 5 and 10 meters below the surface. A mercury U-tube manometer inside the biosphere attached to the biosphere surface which is designed to indicate the water pressure outside. It is located at 10 m deep as shown in Fig 2. The air pressure inside the biosphere is known to be 765 mm Hg. 10 m 735 mm Seawater 360mm Mercury -Shell wall Fig 1 Nemo's garden. Fig 2 Sketch of the biosphere. 1) Based on the readings given in the illustration, determine the atmospheric pressure at the ocean surface (Assume the seawater density if 1024 kg/m³).

Expert Solution
Step 1

Let atmospheric pressure of these bubbles at ocean surface be Pat.

And at 10 lm depth, pressure due to sea water be Psea

Given, 

Large balloons are at a depth of 10 m.

Density of sea is 1024 kg/m3

Specific gravity of mercury is 13.6

Unit weight of water is 9.81 m/s2
