Reducers are devices that connect pipes of different cross-sections. A pipeline has a reducer that connects a 3.0 inch diameter pipe to a 2.0 inch diameter pipe. If water in the large pipe flows at 10 cm/s, how quickly does water flow in the narrow pipe?
A pipeline consists of sections of different cross-sections. Oil flowing in the pipeline fills all cross-sections completely. A section Y of the pipeline has a cross-sectional area of 1.15 m2 and the velocity magnitude at that point is 1.8 m/s. Determine the volume delivered to a tank every hour at the pipeline's terminal.
A water bottling plant uses a pump that fills 900 0.500L bottles every 5 minutes. A gauge connected to the pipe originating from the pump at point A reads 135 kPa and the pipeline cross-section at the point is 20.0 cm2. Point B is elevated by 2.0 m from point A and the pipe cross-section is 5.0 cm2. Determine the volume (in L/s) passing through a fixed point in the pipeline, and the speed of the water at points A and B.
A sprinkler head has 41 openings used to sprinkle water. The openings are 1.5 mm wide. The sprinkler head is supplied with water from a 1.0-inch diameter hose pipe. If water flows at 2.0 m/s in the hose, calculate the speed of the water jets leaving the sprinkler head.
A water tank contains a large volume of water. Three pipes, each with a radius of 2.54 m, drain water from the tank at a combined rate of 8.0 × 107 gallons/h. Assuming the pipes carry equal volumes, how fast does water move in the pipes?
Capillary action causes water to rise in a tube due to adhesive forces between water and the walls of the tube. Suppose a capillary action pump moves water through a compound pipe with a net flow rate of 50 g/h. If the compound pipe has 3500 bores each of diameter 600 μm, find the water speed (in mm/s) in the bores. Assume the water is salty with a density of 1010 kg/m3.
A hydraulic piston has a diameter of 4.45 cm and a volume of 0.398 L. It is supplied/drained of hydraulic fluid using a pipe of diameter 1.27 cm. Suppose fluid from the piston is drained into a reservoir whose pressure is 120 mmHg, and if all the fluid is sent back to the reservoir in 2.5 s, determine the speed of the hydraulic fluid as it flows through the pipe.
