Question:

Water flows from tank A to tank B (Figure P4.1.9), and the water surface elevation difference is 60 feet. Assume the water temperature is 68°F, the pipe material is cast iron, and the pipeline has the following characteristics:
Large pipe: l,000 ft long(D = 16in.)
Bends: four (R/D = 4 in large pipe)
Small pipe: 1,000 ft long (D = 8 in.)
Expansion: sudden

Figure P4.1.9
Determine the system's existing flow rate. What percentage increase in the flow would occur if the 8-in. line were completely replaced with the 16-in. pipeline?
