Q5. A 2500 ft long, 2 ft diameter pipeline conveys water from a hilltop reservoir to an industrial site.The pipe is made of ductile iron, has an outside diameter of

2.25 ft, and has expansion joints. The flowrate is 30 cfs. Determine the maximum water hammer pressure (in psi) that is likely to occur if the downstream flow valve is closed in 1.05 sec. Also determine the water hammer reduction (in psi) if a diverter is added that reduces the flow rate from 30 cfs to 10 cfs almost instantly on valve closure.
