Unformatted text preview: composition is 4% water and 96% KNO3 Basis: 10 4 kg/h is the fraction of KNO 3 in that stream % given is the % by weight First, do overall balances to get total mass of C and W. Then, do balances on equipments to get total mass of R and M. Problem 3 12.8, p.382. Sea water is to be desalinized by reverse osmosis using the scheme indicated in Figure P12.8. 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 (D) c) The fraction of the brine leaving the reserve osmosis cell (which acts in essence as a separator) that is recycled. % given is the % by weight Do overall balances to get mass flow rate of D and B. Then balances on equipments. Part c) asks for ratio of R/C....
