The pump in the figure draws water from a reservoir. At point A on the suction pipe an open manometer shows a vacuum of 290 mm of mercury, while a pressure gage at B reads 16 m of water. The total head loss of the pipes is 0.27 m. When the measured flow is 40 liters/sec, the input horsepower to the pump is found to be 16.4 hp. Compute the efficiency of the pump. Dia. of pipe is 150 mm for both suction and discharge pipes.

Question 4: H₂=4 m f=0.15 D₁ = 50 mm H₁ 4 m 25 m L = 100 m A. Two tanks A and B were connected by a 50 mm-diameter pipe (f=0.15) that is 100 m in length. Calculate the total flow between the two tanks. B. A pipe of 200mm diameter (f-0.01) and length X is to be connected in series to replace X length of the 50mm pipe. If the purpose is to increase flow by 50%. Find Length X. ***** La=X f=0.01 D. = 200 mm

Please answer, hydraulics. Thanks
The pump whose characteristics are: H, = 80 – 600V²2 %3D n = -1500V² + 700V Elevation = 230 m |(2) (1) Elevation = 200 m 1000 m pipe 40 cm in diameter Pump Figure Q3 is used to pump water (µ=0.001kg/ms) a distance of 1000 m between two reservoirs the elevations of which are shown in Figure Q3 and remain constant. The pipe is 40 cm diameter commercial steel (ɛ=0.046 mm). Ignoring minor losses and assuming fully turbulent flow. Determine d) The volumetric flow rate e) The efficiency at the operating point
