iwant the sketch plasese very right Example $5\mathrm{.}8$: $($sizing Design of ED module$)$

An ED Plant desalts $120\frac{m^3}{?}$ day of BW at $3\frac{g}{L}.$ This Plant produces

Potable water at $\mathrm{.}5\frac{g}{L}.$ It is configured in $4$ series modules. The density

of current $($i$)$ is $10m\frac{A}{c}{m}^2,$ Faraday efficiency is $=0\mathrm{.}75$ and the

useful area of membrane is $=0\mathrm{.}8.$

The elementry cells has dimension $(50**50)C{m}^2$ and $400{}_m$ as thickness.

$(1).$ Draw in free hand the sketch of this unit.

$(2)-$ Calculate in of extract salt.

$(3)-$ Determine the number of cells.

$(4.)$ Calculate the velocity.

$(5).$ Calculate the energy required be this unit.

Take: $(F=96500\frac{c}{?}$ equiv. $9$;${}_{}=58\mathrm{.}59\frac{g}{m}ol$;$u=1\mathrm{.}2$ Volt$)$
