Questions regarding concentration calculation
Thread Content
I would like to ask everyone here a simple calculation question: For 1 cubic meter of brackish water with a density of 200 g/L, what happens to its volume when it becomes saturated at a density of 310 g/L? Does the volume increase, decrease, or remain unchanged compared to 1 cubic meter? To adjust the salinity using light saltwater, if the concentration of the light saltwater is 200 g/L and it needs to be increased to 310 g/L, how many kilograms of solid salt (assuming 100% purity) are required per cubic meter of light saltwater? When working on such simple calculation problems, does everyone consider the density of fresh brine and saturated brine? Please share your opinions.
As the concentration increases, either water is removed or salt is added. When water is removed, the overall volume decreases. If salt is added, the water remains unchanged. It’s difficult to calculate the amount of salt when there is no density added.
