Question

(2.) The air pressure above the liquid in figure is 1.17 atm. Thedepth of the air bubble in the liquid is 47.5 cm and the liquid'sdensity is 808 kg/m^3. Determine the air pressure in the bubblesuspended in the liquid. The acceleration of gravity is 9.8 m/s^2.Answer in units of Pa. (1.) The compression strength of concrete (the maximum pressurethat can be exerted on the bas of the structure) is 1.4 x 10^7 Pa.What is the height of the tallest cylindrical concrete pillar witha radius of 53 cm that will not collapse under its own weight? 1m^3 of concrete weighs 53000 N. Answer in units of m.
(2.) The air pressure above the liquid in figure is 1.17 atm. Thedepth of the air bubble in the liquid is 47.5 cm and the liquid'sdensity is 808 kg/m^3. Determine the air pressure in the bubblesuspended in the liquid. The acceleration of gravity is 9.8 m/s^2.Answer in units of Pa.

Explanation / Answer

(1) = h * d   where = max pressureyou've been given and d = the density of the concrete. Work the algebra and you get h = /d
