For the figure shown below, a pipe connects two reserviors. An 8 inch pipe (blue in the figure) exits the upper reservoir with a flush square edge entrance, is 264 feet long, and has 2- long-radius $90^{?}$ elbows $(k=0.6$ ) and a swing check valve (green on the blue pipe, $k=$ 2.5). The 8-inch pipe suddenly transitions to an 12 -inch pipe (green in figure) for another 350 feet. There are $2?45$ bends $(k=0.4)$ and an Angle valve fully open (red in the figure, $k=5$ ) in the 12 -inch pipe. If the flow reading is $1,500\mathrm{GPM}$, what is the total head loss for the system? For the previous problem, if the water level in the upper reservoir decreases and the pipe age increases the friction factors, as shown in the figure below - what will the flow rate be, in GPM? Keep the same minor loss coefficients.
