SC NE | 28% is 7 parts 32%, 1 part water. So 4500 x 11.06= 49770. 49,770 is .875 of your total desired about of 28% so 49770/.875 = 56,880 total 28%. 56880*.125= 7110 lbs of water. 7110/8.34 = 852 gal of water.
Your formula is figuring 1/8th of the 32% amount as water instead of 1/8th of the total 28% amount. You'd actually be making 28.44%, which in the grand scheme of things, isn't much different. | |
