Water at 20 C is to flow out of a settling pond to a drain trench through 100-m equivalent length of 100-mm-i.d. galvanized pipe. The level of the pond is 10 m above the discharge end of the pipe. Find the flow rate of water in m3 /min. 2.6. Water at 20 C flows from the base of a large storage tank through a smooth horizontal pipe (100 mm i.d., 1 km in length) at a velocity of 1 m/s. That is not fast enough. How much pipe must I saw off to get 2.5 times the velocity through the pipe? Ignore kinetic energy and entrance effects.
