A D1 = 0.80 in D2 = 0,04 in A syringe in the figure contains fluid of s.g. 1.05. If the plunger is pushed in steadily at 0.125 in/s, what is the exit velocity. Assume no leakage past the plunger. * 0.0317 ft/s 0.0417 ft/s 0.0517 ft/s O 0.0617 ft/s 5 If the velocity in a 12-in diameter pipe is 1.60 ft./s, what is the velocity in a 2.5-in diameter jet issuing from a nozzle attached to the pipe? * 7.805 m/s 0.7805 m/s 78.05 m/s 0.07805 m/s

A cup is a cylinder with a diameter of 9.87cm and is 30cm tall. The hole is 1.44 from the bottom of the cup and has a diameter of 0.254cm. The cup sits at the edge of a 0.912m tall table. A.) Find the velocity of the water leaving the hole when the cup is full. B.) How far away from the table does the water hit the floor?

Given a cylindrical container with a small 0.2 cm diameter hole a distance of 2 cm from the bottom, devise a method for determining the velocity of the water that would flow out of the hole? You only have rulers and a stopwatch. Describe your method here. Sbiect

1. Fluid Flow: Water runs into a fountain, filling all pipes, at a steady rate of 0.750 cubic meters per second. How fast will it shoot out of a hole 4.50 cm in diameter?

9. A dairy farmer notices that a circular water tank near the barn has become rusty and now has a hole near the base. The hole is 0.30 m below the level of the water that is in the tank. If the top of the tank is open to the atmosphere, what is the speed of the water as it leaves the hole?   a. 1.7 m/s       b. 3.0 m/s       c. 2.4 m/s       d. 2.8 m/s       e. None of the above

Bird bones have air pockets in them to reduce their weight—this also gives them an average density significantly less than that of the bones of other animals. Suppose an ornithologist weighs a bird bone in air and in water and finds its mass is 45.0 g and its apparent mass when submerged is 3.60 g (the bone is water light) a. What mass of water is displaced? b. What is the volume of the bone? c. What is its average density?

You have three objects of varying shapes and sizes: Object 1 is a rectangular block of tin. Object 2 is a cube of aluminum. Object 3 is a sphere of copper. a. the density of tin is 5.75g/cm2. What is the mass of object 1 in kg if the rectangular block has a volume of 1.34L? b. what is the volume in cubic inches of object 2 if the cube of aluminum 7.58 inches on a side? c. what is the mass in kg of object 2? the density of aluminum is 2.70g/cm3 d. what is the volume in cm3 of object 3 if the sphere of copper has a diameter 8.62cm? the volume of the sphere is 4 {pi}^3/3 e. what is the mass in kg of object 3? Copper has a density of 8.96g/cm3

A piece of copper has a mass of 2.6 kg. a.What is the volume of this piece of copper?  b.The copper is then totally submerged in water. What is the buoyant force acting on it?  c. What is the piece of copper’s apparent weight in the water?

Q1: A water pipe narrows from a radius of (R1=5 cm) to a radius of (R2=2 cm. If the speed of the water in the wide part of the pipe is (2 m/s). What is the speed of the ?water at the narrow part
