Consider the U-tube manometer shown in the figure. Both ends of the U-tube manometer is open to atmospheric pressure. The left and right arm of the manometer has a cross-sectional area A1 = 8 cm2 and A1 = 4 cm2, respectively. The left figure illustrates the U-tube when mercury (ρHg =13.6 g ⁄ cm3) is poured into it. The right figure shows the U-tube manometer when 90.0 g of water is poured in the right arm. (a) Determine the length of the water column in the right arm of the manometer and (b) the distance h the mercury rise in the left arm of the manometer

A cylindrical storage tank has a cross sectional area A1=1.5 m². The tank is set up vertically on the ground and filled with V=7.5 m³ of water. There is a valve at the bottom of the tank with an internal cross sectional area of 1.5 cm². What fraction of the total volume will be drained in the first 50 minutes after the valve is opened?

Part A: The human body typically contains 4.9 L of blood of density 1060 kg/m^3 . How many kilograms of blood are in the body? Part B: The average blood pressure is 1.30×104 Pa at the heart. What average force does the blood exert on each square centimeter of the heart? Part C: Red blood cells have a specific gravity of 5.0 and a diameter of about 7.5 μm. If they are spherical in shape (which is not quite true), what is the mass of such a cell?

Water is flowing into a factory in a horizontal cylindrical pipe with a radius of 0.0193 m at ground level.This pipe is then connected to another horizontal cylindrical pipe with a radius of 0.0360 m on a floor of the factory that is h = 12.6 m higher.The connection is made with a vertical section of pipe and an expansion joint.Determine the volume flow rate that will keep the pressure in the two horizontal pipes the same. m3/s

A submersible vehicle is in ocean at a depth of 26.2 m. What is the absolute pressure (in Pa) at this depth? The density of the water in the ocean is 1.00 X 103 kg/m³, and the air above is at a pressure of 101.3 kPa. Submit your answer in exponential form.

An​ outdoor, rectangular pool on campus is 4.5 meters​ [m] in width and 7.5 meters​ [m] in length. You may assume the depth of the pool is constant. If the pool is filled with pure​ water, the total pressure probe at the bottom of the pool reads 16.5 ​pound-force per square inch​ [psi]. What is the volume of the water in the pool in units of kiloliters​ [kL]?     Length Force Mass Pressure 1 ft=12 in 1 N=0.225 lbf 1 kg=2.205 lbm 1 atm=101325 Pa 1 in=2.54 cm   1 slug​ = 14.5939 kg 1 atm=14.7 psi 1 m=3.28 ft   Density of water=1000 ​kg/m3 Surface pressure=1 atm

A Venturi meter is a device for measuring the speed of a fluid within a pipe. The drawing shows a gas flowing at speed v2 through a horizontal section of pipe whose cross-sectional area is A2 = 0.0937 m2. The gas has a density of ρ = 1.30 kg/m3. The Venturi meter has a cross-sectional area of A1 = 0.0234 m2 and has been substituted for a section of the larger pipe. The pressure difference between the two sections is P2 - P1 = 149 Pa. Find (a) the speed v2 of the gas in the larger original pipe and (b) the volume flow rate Q of the gas.   I posted it just now and recieved the wrong answers so i'm asking again. The answers are not A) 1.87 and B) 0.157.

While taking a shower, you notice that the shower head is made up of 44 small round openings, each with a radius of 2.00 mm. You also determine that it takes 5.00 s for the shower to completely fill a 1.00-liter container you hold in the water stream. The water for the shower is pumped by a pump that is 5.50 m below the level of the shower head. The pump maintains an absolute pressure of 1.50 atm. Use g = 10 m/s2, and assume that 1 atmosphere is 1.0  105 Pa. (a) At what speed does the water emerge from the shower head? (b) What is the speed of the water in the pipe connected to the pump? (c) What is the cross-sectional area of the pipe connected to the pump?

A teenager in a large pool at a certain depth D, equipped with a full scuba gear, takes enough air from his tank to fully expand his lungs then swam up to the surface. During the ascent, the teenager failed to exhale which is not advisable. The difference between the external pressure and the acquired pressure in his lungs is 8.7 kPa. Determine the depth D. O 29 m 0.89 m O 9.5 m 8.7 m

A 2.5-m-tall steel cylinder has a cross-sectional area of 1.5 m2. At the bottom, with a height of 0.5 m, is liquid water, on top of which is a 1-m high layer of gasoline, relative density of 0.8. The gasoline surface is exposed to atmospheric air at 101 kPa. What is the total mass of the liquid in the cylinder? 2000 kg O 1250 kg O 3250 kg O 1625 kg
