A new generation of RO module $($Lp$=0\mathrm{.}5$ m$^2.$ m $^2*$ at $*$ m $^2*$ Delta$*$x $*$ y $^2)$ operates at low pressure, it is used to desalt brackish water. The feed flow rate is $1200$ m$^2.$ Day. The plant operates at triangle P $=13$ atm. The recovery ratio of the plant is $40\%.$ The polarization concentration $($y$)$ is $1\mathrm{.}2.$ In order to adjust the product, a fraction of feed blend's the permeate with a blend ratio of $11\%$

a$)$ Sketch a drawing of this plant

c$)$ Compute the area of the membrane.

Take: $-$R$=8\mathrm{.}206^*10^5*$ atm $*$ m $^3/$ mol K$./$ T $=300$K
