Seawater is to be desalinized by reverse osmosis using the scheme indicated in Figure. Use the data given in the figure to determine (a) the rate of waste brine removal (B), (b)
the rate of desalinized water (called potable water) production (P), and (c) the fraction of the brine leaving the reverse osmosis cell (which acts in essence as a separator) that is recycled.
