Q2/ Three pipes are connected in parallel as shown in Fig. No. (2). Pressure head at junction A is 70 (m column of water) and at junction B is 46 (m column of water). For all pipes f = 0.02 and hi is neglected. All pipes are located at the same horizontal level. 1- Find the flow rate of water through each pipe (Qı, Q2 and Q3). 2- Find flow rate of water enters junction A and flow rate of water enters junction B.

I need help with this question: Q. A sprinkler system pumps water through a large pipe inlet with a diameter (d1). The then breaks into N narrow Pipes (which have a diameter, d2, and a length, L2), before the water is released to the atmosphere, as shown in the figure. The entrance to the small pipe from the large pipe has a loss coefficient of KL. You may assume the flow is laminar and fully developed everywhere in the system, and that any changes in height are neglible.  (The viscosity is NOT negligible) a) Find an expressin for the velocity of water leaving the sprinkler b) Find an Expression for the gauge pressure at point A, a distance L1 upstream of the narrow pipes. Express your answer in terms of the flowrate, Q. c) 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…

Water at 25°C is pumped at 1800 gal/min from the lower to upper reservoir, as shown in Figure below (Zı = 30 ft and z2 = 180 ft). Pipe friction losses are approximated by hf = 35V/2g, where V is the average velocity in the pipe. The pump is 80% efficient. (a) Find the head loss due to friction, hẹ in ft. in horse power (b) Compute the pump head, h, in ft and the pump power needed, Ppump (hp). Given: Specific weight of water, ywater = 62.4 lb/ft'; 1 ft/s = 448.8 gal/min. Show all calculations. Z2 = 180 ft Z¡ = 30 ft D= 6 in Pump
