A pressurized tank of water is used to create a fountain, as illustrated. Assume that the water's free surface area in the tank is very large relative to the pipe's cross-sectional area, which is circu- lar with diameter d 1.0 cm. The small pipe bend has height = 10.0 cm. At the instant when 0.75 m, H = 2.5 m, and the gauge measures a pressure of Pgauge 20.0 kPa, the water spray reaches a height L above the pipe exit. h = = = Neglecting viscous effects, determine the height of the spray, L.
A horizontal nozzle discharges water into the atmosphere as shown in the figure. the relative pressure at point 1 equal to p1 = 18 kPa. a. A Pitot tube connected to a mercury manometer is inserted into the flow. in the area section A1 indicating a height difference h = 0.01 m. For this reading indicated in the Pitot tube, determine the velocity in the A1 area section of the nozzle. b. For the dimensioning of the anchor block it is necessary to determine the force that the nozzle applies over the fluid. Calculate the component of this force in the x direction. Data: D1 = 0.070 m; D2 = 0.060 m; 0 = 30°; dHg = 13.6 Patm A2 pi Fx A1 Block of anchorage
The plunger diameter of a single-acting reciprocating pump is 115 mm and the stroke is 230 mm. The suction pipe is 90 mm in diameter and 4.2 m long. If cavitation takes place at the suction head of 4 m, the barometer stands at 10.3 m of water, and the water level in the sump is 3 m below the pump cylinder axis.1. Find the maximum allowable speed to operate the pump
Problem 5. The fully-developed velocity profile for laminar flow in a pipe is very different from that for turbulent flow. For laminar flow, the velocity profile is parabolic (where is centerline velocity): V=1-(+)² For turbulent flow, the time averaged velocity profile can be approximated by a power-law profile: = (1-) Find the ratio of average velocity to centerline velocity, V/Ve, and the dimensionless radial location, 1* = r/R. where you would need to place a Pitot tube if it is to measure the average velocity in the pipe for (a) laminar flow and (b) turbulent flow with n = 6.0 at Rep = 20,000. NOTE: For the integration of the turbulent profile, let r* = r/R and y* = 1 - *.

Calculate the pressure drop across the pipe (Pinlet – Poutlet) from the HaganPoiseuille law when R=0.1m and L=1 m.
A pipeline of constant 0.6 diameter with its centerline in the horizontal plane turns through an m U2 of 75° (Figure angle pipeline carries water at the rate of 0.85 m3/s. A pressure gauge at 3). The she bend indicates that the pressure is equivalent to 41.3 m of water. Calculate the force exerted U1 on the bend by the water and the direction it acts. Fiaure 3 1080 ace

Find the gage pressure at the throat. Find the absolute pressure at the throat. Does cavitation occur? Neglect any losses and assume ideal conditions.
The pipe flow in figure is driven by pressurized air in the tank. What gage pressure (P1) is needed to provide a water flow rate (60 m/h) take (v = 1.15*10 m2/sec).If the (P1 =700Kpa) and the fluid specific gravity is (0.68).estimate the viscosity of the fluid if the flow rate is ( 27 m/sec). 30 m Smoxoth pipe: d = 5 cn Open jet 80 m 10 m - 60 m 86
