Water is supplied at a rate of 100 ft? 5-1, pressure of 50 psi to a turbine through a 5 ft 2 cross-sectional area pipe. The exit conditions are: Water discharges through a pipe of cross-sectional areas 2 ft2 into the atmosphere. The turbine develops a power of 500 hp. The total head loss in this system is 10ft. Assume density of water is 62.8 lbf/m3 Part 1: The velocity with which waters discharges into the atmosphere is ft s-1...
Consider water flowing to three faucets in a building through the very simple plumbing network shown below. Every section of pipe in the figure is 25 ft long. Ali of the piping is nominal half-inch type L copper piping. The inlet pressure to the main pipe is constant at 50 psi and the pressure of the water leaving each faucet is 0 psi. The water has a temperature of 140°F. For the purposes of this analysis assume that there are...
According to fire regulations in a town, the pressure drop in a commercial steel, horizontal pipe must not exceed 2.0 psi per 50 ft of pipe for flow rates up to 250 gal/min. If the water temperature is never below 50˚F, what diameter pipe is needed?
4. The discharge pressure gauge reading is 5 lb/in2 (psi) for the pumping system shown in the sketch below, with the outlet nozzle discharging a 2-inch diameter stream of water directly to the atmosphere. The gauge pressure at the pump suction inlet at the point of incipient cavitation is (-2,071.12) lb/ft, i.e., for vapor pressure of water at 68° F of 50.54 lb/ft2 absolute, and standard atmospheric pressure 30 in Hg. Friction losses in the suction piping from the reservoir...
• The diameter of a pipe carrying water changes gradually from 6 in. at A to 18 in. at B. A is 15 ft. lower than B. What will be the difference in pressure, in psi, between A and B, when 6.2 cfs is flowing, loss of energy being neglected.
The pressure at section (2) shown in the figure is not to fall below 50 psi when the flowrate from the tank varies from 0 to 1.0 cfs and the branch line is shut off. Determine the minimum height h of the water tank (note: minor losses need to be considered). 10 ft h All pipe is 6-in.-diameter plastic (€/D = 0), flanged fittings 6 ft Branch line (2) Main 1 line 2000 ft 1000 ft with 10 90-degree elbows...
The sketch shows a system used to spray polluted water into the air to increase the water's oxygen content and to cause volatile solvents in the 6. water to vaporize. The pressure at B of the nozzle must be 25 psig for proper nozzle performance. The pressure at point A (the pump inlet) is -3.5 psig. The volume flow rate is 0.5 ft3/s. The dynamic viscosity of the fluid is 4.0 x 10 Ib-s/ft?. The specific gravity of the fluid...
CE 3305 Exam1 Fall 2017 4. The Figure below is a part of piping system where water at 50°F flows up AB as shown to the right along BC as shown. The mean pressure and velocity at A is 53.6 psi and 6 fps, respectively. Find the pressure at C. The head loss due to pipe friction from A to C is 3 ft and then flows 120 in Pressure at C
Water at gauge pressure of 3.8 atmospheres at street level enters an office building at 0.60 m/s through a 5.0 cm diameter pipe. The pipe tapers down to 2.6 cm in diameter by the top floor of the building, 18 m above street level, where a faucet has been left open. Calculate the flow velocity and gauge pressure inside the pipe on the top floor. Ignore friction within the fluid.
(b) Water flows under gravity between two reservoirs through a pipe of length 5000m. The diameter of the pipe is 0.2 m and the roughness size is 0.04 mm. The water levels in the two reservoirs are maintained with a difference of 50 m. Determine the discharge through the pipe. Neglect all minor losses. Use the attached Moody diagram for estimation of friction factor. (10 marks) (c) In (b), now include entry loss at the upper reservoir with loss coefficient...
