Determine the level of water that must be maintained in the tank shown in the figure, to produce a volume flow rate of 0.15 m3/s of water at 20 C. Consider: The pipe is made of wrought iron with an internal diameter of 100 mm and 80 meters in length. The road has a KL of 0.04 Elbows are standard with flanged joints The water is discharged into the atmosphere The base of the tank is 20 meters above the level of the pipe outlet.
