- A centrifugal pump as shown in Figure below has a 100 mm diameter suction pipe and a 75 mm diameter delivery pipe. When discharging 15 L/s of water, the inlet water mercury manometer with one side exposed to the atmosphere recorded a vacuum deflection of 198 mm of Hg; the mercury level on the suction side was 100 mm below the pipe centerline. The delivery pressure gauge, 200 mm above the pump inlet, recorded a pressure of 94.666 Kpa. The measured input power was 3.2 kW. Calculate the head added by the pump in m.arrow_forwardWater is to be pumped to an atmospheric rooftop storage tank atop a 5-story building, 75 feet above ground-level. A pump station is located at the ground-level. The suction line is a 2-inch ID commercial steel pipe tapped into a municipal supply line maintained at 50 PSIG 5 feet below ground-level. The discharge line is 1.5-inch ID commercial steel, and the total length of pipe is approximately 100 ft. There are two ball valves, a water meter, and gate valve on the discharge line. Determine the pump head required to deliver 40 GPM and the pump power that must be supplied to the water. If a pump is required, what is the motor power required if the pump operates at 55% efficiency?arrow_forwardA pump delivering 5000 g.p.m. of 60° F. water has a 16-in.-diameter suc- tion pipe and a 14-in. discharge pipe. The suction vacuum gage, which is 3 in.) below the pump centerline, reads 5 in. of mercury (below atmospheric pressure). The discharge gage, which is 18 in. above the pump centerline, reads 10.6 lb. per sq. in. ga. What is the head of the pump? The specific gravity of mercury is 13.6.arrow_forward
- Topics: Fundamental of fluid flow Oil (SG=0.82) entering a pump through an 8-inch diameter pipe at 4 psi has a flow rate of 3.5 cfs. It leaves the pump through a 4-inch diameter pipe at 15 psi. Assuming that the suction and discharge sides of the pump are at the same elevation, find the horsepower delivered to the water by the pump (550 lb.ft/s = 1 HP). Illustrate the problem and show your complete solution.arrow_forwardInorder to achieve a liquid flow rate of 500 gal/min with a maximum pressure difference of 42 psi, calculate the value of valve flow coefficient.

- Measure the volumetric flow rate of water coming out of a faucet. Also determine the average velocity of water leaving the faucet.arrow_forwardAnswer this as fast as you can but answer should be correct (correct answer is priority) Air leaks slowly to atmosphere from a pressurized tank at 19 bar (gage) and 27°C through a hole of diameter 2 mm. The tank volume is 1 m3. Atmospheric conditions are 100 kPa and 27°C. Determine the time for the tank pressure to decrease to 100 kPa (gauge).arrow_forwardExplain how an incorrect flow rate setting (too high or too low) on a pressure-limited time-cycled ventilator affects the volume delivered in terms of neonanatal/pediatric ventilation.arrow_forward
- 10 m3/min of free air is compressed to 8 bar gauge. What will be the volumetric flowrate of air at the compressor outlet if polytropic coefficient of air is 1.3 ?arrow_forwardFigure 8.18 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 water to vaporize. The pressure at point B just ahead of the nozzle must be 25.0 psig for proper nozzle performance. The pressure at point A (the pump inlet) is -3.50 psig. The volume flow rate is 0.50 ft/s. The dynamic viscosity of the fluid is 4.0 x 105 lbs/ft². The specific gravity of the fluid is 1.026. Compute the power delivered by the pump to the fluid, considering friction energy loss in the discharge line.arrow_forwardA pump discharges water at a rate of 10 fps with an internal pipe diameter of 3 inches What is the level of water after 15 minutes in a cylinder tank 10 ft in diameter and 12 ft higharrow_forward
