Question n$3$: CLO$4$ Reverse Osmosis $($Chapter $4)q,$

A spiral wound RO module operates under an applied pressure of $20$ bars and a temperature of $35C,$ it was used to desalt brackish water at $9\frac{g}{L}$ and producing $100\frac{m^3}{h}r.$ The membrane has a retention $R^0$ equal to $99\%.$

Take:

$\backslash$table$[[L{p}_p(\frac{m^3}{m^2}*d\frac{*}{b}ar),h(m),D(\frac{m^2}{s}),M_w(\frac{g}{m}ol).,R(\frac{J}{m}ol.K)$
