A 34-m-high water tower supplies water to a residential area by means of a 20-cm-diameter 800-m-long commercial steel pipe. To increase the pressure head at the delivery point engineers are considering the replacement of 94 percent of the pipe length with a larger (30- cm-diameter) steel pipe connected by a 30° confusor back to the remaining smaller pipe. If the peak water (20°C) demand is 0.10m3/sec, what is the pressure head that would be gained by this strategy?
