Hi,
I have caustic soda solution of 48% (w/w) at SG of 1.5 and need to come up with dilution calculation to a concentration of 31% at SG of 1.33 the vessel is 9000L. What amount of water and NaOH need to be charged? when the sample is low or high in concentration, how much of NaOH (48%) or water need to be charged?
