- An incompressible fluid (water) flows steadily from an open tank. The elevation of point 1 is 10.0m, and the elevation of point 2 and 3 is 2.00m. The cross-sectional area at point 2 is 0.0680 m^2, at point 3 it is 0.0360 m^2. The area of the tank is very large compared to the cross-sectional area of the pipe. Assuming that Bernoulli’s equation applies, compute: (a) The discharge rate in cubic meters per second;(b) The gauge pressure at point 2.Water flows through a rubber hose 2 cm in diameter at a velocity of 4 m/s. (a) What must be the diameter of the nozzle in order that the water emerge at 16 m/s? (b) What is the rate of flow in cu.m per minute?A pump is installed to deliver water from a reservoir of surface elevation zero, to another of elevation 290 ft. The 10 inch-diameter suction pipe (f=0.022) is 90 ft long and the 8-in-diameer discharge pipe (f=0.028) is 4900 ft long. The pump characteristic is defined by hp= 365-20Q2 where hp, the pump head, is in feet and Q is in cubic feet per second. What is the rate at which the pump will deliver the water?
- Air flows through a duct at 2,700 cubic feet per minute (CFM). After several feet and a few vents, the air-flow decreases to 1,890 CFM. What is the percent drop that has occurred? (Simplify your answer completely.)please answer A pump impeller rotating at 1400 rpm has an outside radius of 21 cm, the vane outlet angle β2 is 158° and the radial velocity at the outlet Cr2 is 4 m/s. Assuming radial flow at inlet, draw the theoretical outlet velocity diagram and calculate the various velocities and angles.( A)What is the theoretical head Ho, in meters, assuming that the circulatory flow coefficient η∞ = 1.,(B)In the preceding example; assume a deviation of 10° applied to β2 due to circulation after the modern theory. The flow is 30 lit/s. After drawing/illustrating the velocity diagram, find the theoretical head Ho, in meters, assuming radial flow at inlet, neglecting the deviation in inlet velocity diagram. (c)Assuming that the mechanical efficiency ηmech = 0.95, the hydraulic (or manometric) efficiency ηman = 0.8, find the required break horsepower to drive the pump.Chlorine gas is moving through a pipeline at a rate of 200 kilogram per hour while being pressured at 5 psig and operating at 800 F. If the pipe has a diameter of 5 inches, what is the flow velocity, expressed in meters/second?
- Find an expression for the velocity of water leaving the sprinkler. Find an expression for the gauge pressure at point A, a distance L1, upstream of the narrow pipes. Express the answer in terms of the flowrate, Q. The inner diameter of the first segment of the pipe is d1=10mm, the inner diameter of the second set of pipes is d2=1mm, with N=25. The flowrate through the sprinkler is Q=0.2 L/s. Flow in pipes typically becomes turbulent when the Reynolds number exceeds 2000. Comment on the accuracy of the assumption that the flow could be treated as laminar everywhere. May be assumed water has a density of 1000kg/m^3 and a viscosity of 1mPa s.Aiming a 1.69 in diameter garden hose straight up, forms a “bubbler fountain” that you could easily drink from (but you shouldn’t because of bacteria, etc.). The water flows out the hose and down the sides. If the water has a density of 63.1 lbm/ft^3 and a viscosity of 0.0119 g/cm*s, what is the thickness of the water film (df) (in cm) if the flow rate of water is 6.42 in^3/s? For simplicity, assume the film is thin enough that you can use rectangular coordinates.Pipe A, 30 cm in diameter, branches into two pipes B and C. Pipe B is 15 cm in diameter and pipe C is 7.5 cm in diameter. If the flow in A is divided as follows 2/3 goes to B and 1/3 goes into C, what is the discahrge in pipe A, if the velocity must not exceed 3 m/s in any of the pipes?
- Suppose that you are willing to determine the diameter of the water jet impinging to the sink from the kitchen tap.The tap is produced to supply three different flow rates of the low, medium, and high. For each flow rate level, waterthat comes from the tap fills the beaker with a volume of 30 mL in 10 s, 6 s, and 2 s, respectively. The outlet of the tapis 13 mm, and the distance between the tap outlet and the sink is 53 mm. Determine the diameters of the water jetimpinging on the sink at three given flow rates.Suppose a u-bend is redirecting a flow of water. The water enters flowing to the right at 10 m/s. The u-bend completely reverses the direction of the flow, so the water leaves flowing to the left. The area of the u-bend is constant, a circular cross-section of 0.12 m. The pressure in the fluid is measured at 50 kPa. The length of the u-bend is 0.46 m. Find the force, including magnitude and direction, to hold the u-bend in place.Chlorine gas enters a 30-mm ID pipe at 15 m/s, and exits a wider pipe, at 85-mm ID. What is the average velocity through the exit pipe (in m/s)?
