200mmø 690mm 300 mm 400 mmø 金Ho0 Z Hg (13.6) A 200mm diameter venturi meter is installed in a 400mm diameter vertical main pipe as shown. If the deflection of mercury (SG = 13.6) at the manometer reads 300mm and the vertical distance between point 1 and point 2 is 690mm, determine the discharge in the system assuming a head loss of 600mm.

For the setup shown in the figure :
Determine the flow distribution of water in the system shown in Figure below. Assume constant friction factors, with f= 0.03. The head-discharge for the pump is Hp = 70 m el 50 m Pipe L (m) D (mm) ΣΚ el 48 m 1 100 750 850 350 200 200 [2] [4] 3 el 0m [5] 4 500 200 350 250 [1] [3]
Data measured during tests of a centrifugal pump at 2750 rpm are Parameter Inlet, Section Outlet, Section (2) Gage pressure, p (kPa) Elevation above datum, z (m) 120 500 2.5 Average speed of flow, V (m/s) 2.5 3.5 The flow rate is 15 cu.m./hr. and the torque applied to the pump shaft is 85N.m. Evaluate the total dynamic heads at the pump inlet and outlet, the hydraulic power input to the fluid, and the pump efficiency. Specify the electric motor size needed to drive the pump. If the electric motor efficiency is 85%, calculate the electric power requirement
7. Barometeric pressure is 101.3 kPa and vapor pressure of water is 32.4 kPa. Calculate the elevation (in meters) of the tubing end 3 for maximum flowrate through this pipeline. Also sketch the energy line, EL (color red) and the hydraulic grade line, HGL (color blue) on the drawing for this situation. El. 34 Water 150 mm d EI. 30.5
Question 1: For the setup shown in the figure: H = 20 m f = 0.0012 f = 0.0012 D = 250 mm D = 80 mm L = 50 m L = 50 m f = 0.001 D₁ = 150 mm L = 100 m A. Calculate Q in the 150 mm-diameter pipe B. If the NPSHR of the pump is 3 m. Is it feasible to use the pump? You can use: Patm-101 kN/m², and Pvapor = 3.17 kN/m² H₂ = 10 m Pump Q f = 0.0012 D=80 mm L = 50 m Q₁ = 0.2
