Determine the specific energy $($in kW$-$hr$/$m$3$ of drinking water$)$ required for a brackish groundwater reverse osmosis $($RO$)$ desalination process that produces $10,000$ m$3/$day $($or $2\mathrm{.}64$ million gallons per day$)$ of drinking water. The feedwater pumps operate at a pressure of $650$ psi $($or $44\mathrm{.}8$ bar$)$ and have an energy efficiency of $85\%.$ The brackish RO system operates at $75\%$ recovery $($i$.$e$.,$ for every $100$ gallons of groundwater pumped to the front end of the RO system at high pressure, $75$ gallons of drinking water are produced, and $25$ gallons of high$-$salinity $$concentrate$$ waste is produced$).$
