Determine at what depth (in meters) an object must be submerged in the sea, so that there is an absolute pressure equal to 10 atm on it. Remember that 11.2 atm = 101325 Pa, which is the pressure at sea level, and take the density of seawater as 1024 kg / m3.

A salty lake has a relative density of 1.10 .(b) Determine the total pressure at a depth of 7.7 m below the surface.(c) Mercury has a relative density of 13.53 . Calculate the depth of mercury corresponding to the total pressure in part (b).

A submersible vehicle is in a lake at a depth of 32.0 m. What is the absolute pressure (in Pa) at this depth? The density of the water in the lake is 1.00 ✕ 103 kg/m3, and the air above is at a pressure of 101.3 kPa.   Pa (b) The submersible vehicle has a circular window with a diameter of 32.0 cm. What force (in N) is exerted by the water on the window of the vehicle at the depth from part (a)? (Enter the magnitude.)

A meat baster consists of a squeeze bulb attached to a plastic tube. When the bulb is squeezed and released, with the open end of the tube under the surface of the basting sauce, the sauce rises in the tube to a distance h, as the drawing shows. Using 1.013 × 105 Pa for the atmospheric pressure and 1470 kg/m3 for the density of the sauce, find the absolute pressure PB in the bulb when the distance h is (a) 0.18 m and (b) 0.09 m. A cylindrical storage tank has a radius of 1.08 m. When filled to a height of 3.27 m, it holds 13100 kg of a liquid industrial solvent. (c) What is the density of the solvent?
