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. pipe No.(1) Q1 NO. 1 Pipe L (m) (mm) 300 3000 pipe No.(2) Q2 B 2 1300 200 3 2600 250 QA QB pipe No.(3) Q3 Fig. 3

Q2(c) Water flows at a rate of 12 L/s in an 80 mm diameter of galvanized pipe installed in a vertical plane shown in Figure Q2(c). The pipe length from point 1 to point 2 is 85 m, and the 90degree elbow has km = 1.0, while the globe valve has km = 10. Given friction factor, f = 0.0070. Calculate the pressure at point 2.

For a tank, calculate the volumetric flow of water, which comes out through a pipe, the tank is sealed, the depth is h1=2M, Qexit=0.05,substance water Vexit=? and Q=?.

Water (p 1.96- slug) flows through the pipe system below. Data is given below: = ft³ Pipe 1: V₁=1.8 ft, D₁ =2.4 inches, p₁ =24.9 psi Pipe 2: V₂=1.4 t, D₂=1.9 inches 2 Pipe 3: D3=0.7 inches Assume no energy is lost to friction. Find the pressure p3. Report your answer in psi. V₂ V₁ P₁ D₁ D₂ P2 D3₁ V3 P3

Water flows from a large tank through a large pipe that splits into two smaller pipes, as shown in the figure below. The flow can be considered inviscid and steady state. Assume d1 = 1.5 cm, d2 = 2 cm, z = 8.5 m, and h = 3.5 m. Determine the level of the tip of the inclined pipe such that the flowrates exiting both small pipes are equal. Z diameter d diameter d
