A liquid with a density of 1.65 g/cm3 flows from left to right in the pipe, from larger to smaller cross section. The left side's cross-sectional area is 10.0 cm2, and while in this side, the speed of the liquid is 2.62 m/s, and the pressure is 1.20 ✕ 105 Pa. The right side's cross sectional-area is 3.00 cm2. What is the velocity and and pressure?

(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 liquid is flowing through a horizontal pipe whose radius is 0.0301 m. The pipe bends straight upward through a height of 8.80 m and joins another horizontal pipe whose radius is 0.0726 m. What volume flow rate will keep the pressures in the two horizontal pipes the same? Number Units 202

Mercury is poured into a U-tube as shown in Figure a. The left arm of the tube has cross-sectional area A, of 9.8 cm², and the right arm has a cross-sectional area A, of 5.50 cm². Two hundred gra 8 ст of water are then poured into the right arm as shown in Figure b. Water A1 Ag A1 Mercury Densities: Mercury 13.6 g/cm³, Water 1.0 g/cm³ (a) Determine the length of the water column in the right arm of the U-tube. cm (b) What distance h does the mercury rise in the left arm? cm. (c) In figure b, at the level of the dashed line, which side of the u-tube has larger pressure? O Mecure side Water side Same

A water barometer is used to measure air pressure in a duct where the air is being forced to ventilate a building. One end of the barometer is open to the atmosphere, and the other end is open to the inside of the ductwork.  When the tube is bent in the shape of a U, the technician notes that the water level on the side toward the duct is lower than the side toward the atmosphere by 13.4 cm.  What is the pressure difference in N/m2?  The density of water is 1 gm/cm3  or 1000 kg/m3.   Use 9.8 m/s2 for the acceleration of gravity.

An empty graduated cylinder weighs 64.50 g. To this was added 32.0 mL of water (d= 1.00 g/cm³). An irregular piece of lead is submerged in the water, bringing the total volume to 57.4 mL. The mass of the cylinder and all the contents was 406.50 g. Calculate the density of the lead. O 13.5 g/cm3 O 12.20 g/cm3 O 12.2 g/cm3 O 12.2

A person is diving in a lake in the depth of h = 10.5 m. The density of the water is ρ = 1.0 x103 kg/m3. The pressure of the atmosphere is P0 = 1.0 x 105 Pa.

Express the magnitude of the force exerted by water on the top of the person's head F at the depth h in terms of P and A.  d.  Calculate the numerical value of F in N.

A level (horizontal) pipe contains a non-viscous, incompressible fluid with a density 1200 kg/m³ that is flowing steadily. At one position within the pipe, the pressure is 300 x 103 N/m2 and the speed of the flow is 20.0 m/s. At another position, the pressure is 200 x 103 N/m². What is the speed of the flow at this second position?

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.)
