Q $3//$ Solve Problem $2$ by the arithmetic summation method. Ans $//$ V$=1\mathrm{.}97$ ft $/$ s Q$4//$ The equation for the vertical velocity distribution with respect to the water surface is v$=3\mathrm{.}8(4-$y$)^1/2.$ For a depth of flow of $4$ ft$,$ what is the average velocity of flow?$($CE $341$ review$)$ The equation for the vertical velocity distribution in a stream was

found to be given by $u=1\mathrm{.}9y^{\frac{1}{7}}$ where $u$ is in $f\frac{t}{sec}$ and $y$ is the depth $($ft$)$ measured

from the bed. If the depth of flow is $3\mathrm{.}5ft,$ what is the average velocity? What is the

flow per unit width, $q?$
