$($Flowrate$)$ Air blows through two windows as indicated in the figure below. Use equation $B_{\text{o}\text{u}\text{t}}^{}={\displaystyle \underset{\text{c}\text{s}\text{o}\text{a}\text{t}}{\overset{\phantom{}}{}}}bV*hat(n)dA$ with $b=\frac{1}{}$ to

determine the volume flowrate $(f\frac{t^3}{s})$ through $($a$)$ the left window and $($b$)$ the right window.
