5 Hydrostatic pressure

Open Ended

1.     Divers must be careful when working at depth in water and need to carefully control the dissolving of gases in their bloodstream.

 

Calculate the pressure created by a 30 m depth of water given that the density of water is 1000 kg m⁻³ and the acceleration due to gravity 9.8 N kg⁻¹.

2.     The density of sea water is ~1025 kg m⁻³ and the maximum depth of the Atlantic Ocean is ~8500 m (8.5 km).

 

Calculate the water pressure at this depth.

3.    The pressure at the bottom of a storage tank of depth 12.5 m containing a chemical solvent is 306 kPa.

Calculate density of the solvent. Assume that the tank is full.
