Problem $1$:

A water distribution system is designed to supply multiple neighborhoods, as illustrated in the diagram below. The system includes three different pipeline segments connecting an Elevated Water Storage $($EWS$)$ to a Ground Storage Tank $($GST$).$ The diameters of the pipeline segments $($EWS$-$J$1,$ J$1-$J$2,$ and J$2-$GST$)$ are $1100mm,1000mm,$ and $900$ mm $,$ respectively.

Calculate the total discharge flowing from the Elevated Water Storage $($EWS$).$

Determine the flow velocities in each of the three pipeline segments.

How much water is released from the Elevated Water Storage $($EWS$)$ over a period of one hour?

What is the total volume of water that reaches the Ground Storage Tank $($GST$)$ in one hour? Discuss any discrepancies in the volumes calculated.
