Q- A spherical brass shell of mass 2.50 kg barely floats in water such that it is completely submerged with the waterline just at its top. The inside of the shell is completely evacuated. The density of brass is 8600 kg/m3 and that of water is 1000 kg/m3.
(a) calculate the …
Q- A container full of air at atmospheric pressure is 3 feet below the surface in a large body of water; this container is 8 feet high by 3 feet square. A 16-inch ID valve is on the bottom of the container and a 2-inch valve is on the top. A 2-inch ID hose connects to this valve and extends 1 foot a…
Q- A hypodermic syringe is attached to a needle that has an internal radius of 0.3 cm and a length of 3 cm. The needle is filled with a solution of viscosity 2*10-3 Pa.s to be injected into a vein at a gauge pressure of 16.5 mm of Hg.
(a) What must be the pressure of the fluid in the syringe be in …
Q- A hypodermic syringe is attached to a needle that has an inner radius of 0.305 mm and a length of 3.00 cm. The needle is field with a solution of viscosity 2.01*10-3 Pa.s. It is injected in to a vein at a gauge pressure of 16.6 mm of Hg.
(a) What must the pressure of the fluid in the syringe be …
Q- A siphon tube is filled with gasoline and closed at each end. One end is inserted into a gasoline tank 0.20 m below the surface of the gasoline. The outlet is placed outside the tank at a distance 0.50 m below the surface of the gasoline. The tube has an inner cross-sectional area of 4.2*10-4 m2.…
Q- A patient is to be given a blood transfusion. The blood is to flow through a wide tube from a raised bottle to a needle inserted in the vein. The inside diameter of the 3.8 cm long needle is 0.4 mm and the required flow rate is 4 cm3 of blood per minute. How high should the bottle be placed a…
Q- Air is trapped in the lower part of a thin tube that stands vertically with 8cm of mercury in the middle with 12 cm of air trapped below it. The top is open and the system is at equilibrium. What will be the length of the trapped air column if the tube is now tilted so that it makes an angle of 6…
Q- What percentage of an ice cube is under water when it is placed into water? What percentage of an ice cube is submerged when it is placed in a drink that is straight 80 proof whiskey? (80 proof mean that it is 40% alcohol and 60% water.)
(Density of ice ri = 917 kg/m3, density of alcohol rA = …
A 9.0 kg block of metal is suspended from a scale and immersed in water as in Figure. The dimensions of the block are 12.0 cm *9.0 cm *9.0 cm. The 12.0 cm dimension is vertical, and the top of the block is 5.00 cm below the surface of the water.
