System Data:

Overflow elevation: $4030$

Top of pressure zone elevation: $3915$

Bottom of pressure zone elevation: $3800$

Transmission pipeline: $5000$ feet, $12-$inch diameter

Distribution pipeline: $3000$ feet, $10-$inch diameter

Flowrate in transmission pipeline: $2500gpm$

Flowrate in distribution pipeline $1500gpm$

Assume friction factor $"f"$ to be $0\mathrm{.}019$ for the calculations
