Mercury is added to a cylindrical container to a depth d and then the rest of the cylinder is filled with water. If the cylinder is 0.6 m tall and the pressure at the bottom is 1.4 atmospheres, determine the depth of the mercury. (Assume the density of mercury to be 1.36 104 kg/m3.)

A company has several sensors in storage silos to detect the total pressure in the silos to ensure the tanks will not leak. Each tank is designed to withstand a maximum total pressure of 5.7 atmospheres​ [atm]. An engineer wants to use one of the silos to store liquid nitric​ acid, which has a density of 97​ pound-mass per cubic foot [lbm​/ft3​]. If the tank is filled to a depth of 90 feet​ [ft], how much surface pressure in units of atmospheres​ [atm] can be applied to the top of the liquid inside the tank without exceeding the maximum total pressure of the​ silo?

(Figure 1) shows a container with a cross section area of 15 cm² in which a layer of water floats on top of a layer of mercury. A 1.0 kg wood block with a cross-section area of 10 cm² floats on the water. The water depth, measured from the bottom of the block, is 25 cm. A pressure gauge at the bottom of the container reads 20 kPa. Figure 1.0 kg 25 cm h 10 cm² 15 cm² 1 of 1 > Part A = What is the depth dm of the mercury?

(a) A submersible vehicle is in a lake at a depth of 32.4 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.   (b) The submersible vehicle has a circular window with a diameter of 40.0 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.)
