Three brine solutions, B1, B2, B3, are mixed. B1 is one-half of the total mixture. Brine B1 is 2.5% salt, B2 is 4.5% salt, and B3 is 5.5% salt. To this mixture is added 31 lbm of dry salt while 353 lbm of water is evaporated leaving 3,000 lbm of 5.1% brine. Determine the initial amounts of B1, B2, and B3. (Round the final answer to three decimal places.) (a) The initial amount of B1=[ Ibm. (b) The initial amount of B2 = (c) The initial amount of B3 = lbm. lbm.
