Water flows out through a pipe with a cross sectional area of 1.6 m2 without friction at a rate of 3000 L/s (3 m3/s).  Find the velocity of the fluid as it flows out of the pipe, and the velocity of the fluid if the pipe constricts to a cross section of 0.8 m2.

A water line with an internal radius of 5.48 x 10-3 m is connected to a shower head that has 19 holes. The speed of the water in the line is 2.09 m/s. (a) What is the volume flow rate in the line? (b) At what speed does the water leave one of the holes (effective hole radius= 5.67 x 10-4 m) in the head? (a) Number (b) Number Units Units >

Water is flowing in a pipe with a varying cross-sectional area, and at all points, the water completely fills the pipe. At point 1, the cross-sectional area of the pipe is 0.070m2and the magnitude of the velocity is 3.50m/s. (a) What is the fluid speed at points in the pipe where the cross-sectional area is (a) 0.105m2and (b) 0.047m2? (c) Calculate the volume of the water discharged from the open end of the pipe in 1.0 hour.

A 1.2-mm-diameter tube is inserted into an unknown liquid whose density is 960 kg/m3, and it is observed that the liquid rises 5 mm in the tube, making a contact angle of 15°. Determine the surface tension of the liquid.

Air flows through a heating duct with a square cross-section with 6-inch sides at a speed of 4.3 ft/s. Just before reaching an outlet in the floor of a room, the duct widens to assume a square cross-section with sides equal to 13 inches. Compute the speed of the air flowing into the room (in ft/s), assuming that we can treat the air as an incompressible fluid.

(a) If it takes 1.55 min to fill a 23.5 L bucket with water flowing from a garden hose of diameter 2.80 cm, determine the speed at which water is traveling through the hose. (b) If a nozzle with a diameter four-fifths the diameter of the hose is attached to the hose, determine the speed of the water leaving the nozzle.

A water line with an internal radius of 6.89 x 103 m is connected to a shower head that has 12 holes. The speed of the water in the line is 0.982 m/s. (a) What is the volume flow rate in the line? (b) At what speed does the water leave one of the holes (effective hole radius = 3.14 x 104 m) in the head? (a) Number i (b) Number i Units Units
