Outflow from a reservoir with constant surface area and vertical sides is over a spillway $($QC$.$LH$),$ Note: HZ$.$ Analyze $($a$)$ the expression for the time required for the water level to fall from $2$ to $22.($b$)$ How long will it take theoretically for the outflow to cease entirely? $($e$)$ Given the crest of the overflow spillway is $100$ ft long, the value of C$.$ is $3\mathrm{.}45,$ and the constant water$-$surface area is $700,000$ ft$.$ With no inflow, find the time required for the water surface to fall from $3$ ft to $1$ ft above the$$spillway$$level$.$
