Three pipes are connected in parallel. The difference in heads in each pipe is 40 m. Pipes Diameter (cm) Length (m) Friction factor 1 15 500 0.02 2 10 450 0.03 3 20 800 0.025 4. If a fourth pipe 25 cm in diameter and length 1100 m with f = 0.018 were attached at the end of the three pipes, what would be the velocity of the water at the fourth pipe?

A 75-mm diameter pipe is connected to a 100-mm diameter pipe. If the velocity of flow in the 75-mm pipe is 2 m/s, what is the velocity of flow in the 100-mm pipe? What is the flow rate in the 75-mm pipe in m^3/s?

Elevation = 100 ft D¸ = 1 ft (1) l (1) e, = 1000 ft D2 = 1 ft lz = 500 ft B V Elevation = %3D 20 ft (2) D3 = 1 ft (3) Elevation = l3 = 400 ft O ft Three open reservoirs are connected by pipes as shown above. It is assumed that the pipe diameter is equal to the friction factor of 0.03. Because theratio of the LIDpipe is large, the minor losses are ignored. Determine the flow in or out of each reservoir! Draw with sketch 5.
