Water is flowing through a 10-cm diameter water pipe at a rate of 0.2 m^3/s. Now a diffuser with an outlet diameter of 20 cm is bolted to the pipe in order to slow down water that exits into the atmosphere, as shown. Disregarding frictional effects, determine the force exerted on the flange due to the water flow. Density of water = 1,000 kg/m^3. + d = 10 cm D = 20 cm Diffuser
4. An old, rough-surfaced, 2-m-diameter concrete pipe with a Manning coefficient of 0.025 carries water at a rate of 5.0 m'/s when it is half ful. This pipe is to be replaced by a new smooth pipe with a Manning coefficient of 0.012. Determine the diameter of the new pipe if it also is to flow half full with a flow rate of 5.0 m'/s Water initially flowing in the horizontal section of pipe of diameter 12.00 cm shown in...

Water is flowing through a 10-cm-diameter water pipe at a rate of 0.1 m/s. Then, a diffuser with an outlet diameter of 20 cm is bolted to the pipe in order to slow down water as it exits the diffuser to atmospheric pressure, as shown in the given figure. Disregarding frictional effects, determine the force exerted on the bolts due to the water flow. Take the density of water to be 1000 kg/m3 -t- d 10 cmm D = 20...
A horizontal water pipe goes from a large diameter to a small diameter and then back to the first diameter as shown in the figure below. The level of water in the small vertical tubes provides us with information about the water pressure in the two different sizes of pipe. The inside diameter of the larger pipe is 2.85 cm and water travels through both sizes of pipe with a volume flow rate of 1.20 10-4 m3/s. Determine the inside...
Please show all the steps and calculations, thanks Problem 5.4 A short circular pipe with diameter D, has water (p,u) flowing through it from left to right at a volumetric flow rate Q. At the exit a plug with diameter D2 that partially blocks the water flow is inserted (to provide upstream pressure pı (gage) to the pipe and/or to reduce flow rate). Both upstream pressure and flow rate can be measured. (a) Using the conservation equations (mass, momentum) in...
A flow nozzle equipped with a differential pressure gage is used to measure the flow rate of water at 10°C (p 9997 kg/m3 and p 1.307 x 10-3 kg/m s) through a 3-cm-diameter horizontal pipe.
