The rate of flow of water pumped into a pipe ABC, which is 200 m long. is 20 litres/s. The pipe is laid on an upward slope of 1 in 40. The length of the portion AB is 100 m and its diameter is 100 mm, while the length of the portion BC is also 100 m but its diameter is 200 mm. The change of diameter at B is sudden. The flow is taking place from A to C, where the pressure at A is 19.62 N/cm² and end C is connected to a tank. Calculate the pressure at C. Take f=0.008.

Water flows initially from tank A to B through a single pipeline which is 150 mm in diameter and 150 m in length, shown in the figure below. Further development requires that the flow rate is to be increased by 30 % by installing a second pipe in parallel, indicated by the dotted line and 82 m in length, running from A to c. The coefficient of friction for each pipe is 0,015. Determine the diameter of this new pipe. = ? L= 82 m 4 m 0 = 150 mm L= 80 m = 150 mm L = 70 m
The 600 mm diameter pipe conducts water from reservoir A (El. 61 meters) to a pressure turbine (El. 4.60 meters), which discharges through another 600-mm diameter pipe into tailrace B (El. 0 meter). The loss of head from A to the entrance of the turbine (pt.1 ) is 5 times the velocity head in the pipe and the loss of head from the exit of the turbine (pt.2) is 0.20 times the velocity head in the pipe. If the discharge is 708 Liters/second, Determine the efficiency of the turbine if the output power is 480 hp. a. 61.20% b. 69.15% c. 75.72% d. 86.88% e. 89.57%

Problem Consider a cylindrical pipe of length L and diameter D = 2R. The angle that the axis of the pipe forms with the vertical direction is a. Assume that when the fluid enters the pipe its velocity is uniform (i.e., it has the same value over the entire cross-section of the pipe) and equal to U in the axial direction. In the radial and angular directions, the velocity is zero. So, it is: 2 =0: v(r, 0, 2) = Ue, (1.1) Here v is the fluid velocity and e, is a vector of unit magnitude parallel to the coordinate axis z; furthermore, we have assumed that the pipe inlet is located at z = 0. Near the entrance of the pipe, the velocity profile varies in the axial direction. But after a certain entrance length, the profile becomes fully developed, no longer changing with z. The evolution of the velocity profile is sketched in Fig. 1, where, for clarity, the pipe inclination is not shown. The entrance length is denoted by L.. For z > L., the fluid velocity is no longer a function of the axial…

Water flows through a pipe AB of diameter d1= 60mm, which is in series with a pipe BC of diameter d2= 85mm in which the mean velocity V2 = 3m/s. At C the pipe forks and one branch CD is of diameter d3 such that the mean velocity V3 is 2.5 m/s. The other branch CE is of diameter d4= 40mm and conditions are such that the discharge Q2 from BC divides so that Q4= ½ Q3. Determine Q1, Q3, Q4 and d3.

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.
