A large reservoir is to be constructed to provide water to a town and it is located at 100m above the river surface. A pump was placed at the river bank as shown and it pumps water to the large reservoir. At the same time, in order for the reservoir to be constructed, the Engineers promised the indigenous people who lived 20m below the reservoir that they will be provided with water via the pipe shown in red which flows under the influence of gravity. It was also agreed upon that electricity will be provided later to the IP's using the same pipe that supplies water to them. The large reservoir is designed to provide water for about 6000 townspeople and each people requires 100liters of water per person per day El 100m Pipe Properties L= 30m D = 75mm C = 140 Pipe Properties L= 150m D = 250mm e = 0.2mm v = 1.004x10 m/s y = 9.79kN/m El 80m P El Om Determine the following: • What is the flow rate at the pump in m3/s? • What is the power of the motor if the pump efficiency is 84% and the shaft efficiency is only 80% • What will be the power provided to the indigenous people community of the turbine efficiency is only 85% and the motor efficiency is 65%

Please be sure ,If possible mention the assumption that you have made.
What diameter of pipe should be installed to carry 1.42 m³/s of water for 8 km with a loss of head of 1.50 J/N.
pls answer in 3 decimal places. subject: hydraulics engineering
You are drilling an artesian well in a steeped sloped region. You know from previous hydrogeological maps that several springs have been documented altitudes of 1100 - 1110 m. What would you expect if you drill a deep well at 1050m altitude? Dry well since the springs are already pumping the water out Gushing wells with minor fountains Gushing well with major fountains Artesian well with stand still water inside the well
Water flows at the rate of 12 m³/s in a 6 m wide rectangular channel. A hydraulic jump is formed in the channel at a point where the upstream depth is 30 cm (just before the jump). considering acceleration due to gravity as 9.81 m/s² and density of water as 1000 kg/m³, the energy loss in the jump is elisw moting dlu201
A hydraulic lift is used to jack a 960-kg car 42 cm off the floor. The diameter of the output piston is 18 cm, and the input force is 380 N. (a) What is the area of the input piston? (b) What is the work done in lifting the car 42 cm? (c) If the input piston moves 13 cm in each stroke, how high does the car move up for each stroke? (d) How many strokes are required to jack the car up 42 cm? (e) Show that energy is conserved.
Does the hydraulic jump have any application in the industry? Using illustrations, explain the practical use of creating a hump or a sudden drop in the bed of a channel.
