No EXCEL PLEASE!!!!

Solve and plot the flow profile using the direct step method, for the following conditions:

$Q=28\frac{m^3}{(s)},n=0\mathrm{.}032,b=5m,y_{\text{v}\text{e}\text{n}\text{a}\text{c}\text{o}\text{n}\text{t}\text{r}\text{a}\text{c}\text{t}\text{a}}=0\mathrm{.}50m,y_{\text{l}\text{a}\text{k}\text{e}}=1\mathrm{.}20m$

$S_{o1}=0\mathrm{.}7\%,L_1=15m,S_{02}=0\%,L_2=60m,S_{03}=0\mathrm{.}3\%,L_3=240m$

Try to have at least $3$ flow depths per reach. If there is a jump $($or there are jumps$),$ please locate.
