Estimate the delivery when the pump is used to move water between two open reservoirs through $1200 \mathrm{ft}$ of 12-in.-diameter commercial steel pipe containing two $90^{\circ}$ elbows and an open gate valve if the elevation increase is $50 \mathrm{ft}$. Determine the gate valve loss coefficient needed to reduce the volume flow rate by half.
