- The water in a 750 cubic meter treatment water tank is discharged under the influence of gravity to a point 15 m below the tank bottom through a 150 mm diameter commercial steel pipe of 1000 m. If you think that it is a continuous system with a constant water height of 3.5 in the tank, what will be the discharge rate in cubic meters / hour.arrow_forwardThe water level in a tank open to the atmosphere is 20 m above the ground. A hose connected to the bottom of the tank is equipped with a nozzle at the end pointing straight up. In the line leading from the tank to the nozzle is a pump, which increases the pressure of water. If the water jet rises to a height of 27 m from the ground, what is the minimum pressure rise supplied by the pump to the water line?

The discharge point is 20 ft above the centerline of the pump. Frictional and other (contraction, expansion, etc.) losses in suction and discharge lines amount to 1.5 ft head of liquid.

- In a large pumped hydro plant, the head from the turbine to the lake surface is 100m. During a period of 8 hours of excess electricity in the grid the pumped hydro plant pumps water back into the top reservoir.

The height difference between the water level in the tank and the outlet is 50m, and the diameters of the pipes are 50mm and 100mm, respectively.

A pump pumps 0.200 ft3/s of brine solution having a density of 1.15 g/cm3 from an open feed tank having a large cross-sectional area. The suction line has an inside diameter of 3.548 in. and the discharge line from the pump a diameter of 2.067 in. The discharge flow goes to an open overhead tank, and the open end of this line is 75 ft above the liquid level in the feed tank.
