    There is only one kind of water, and it is (mostly) absorbed when it appears in the proximal small intestine.

     

    Thus, the primary factor that determines absorption rate is the rate of gastric emptying to the small intestine; how fast does your stomach move its contents down. A slice of pizza is 40% water, but it will take much longer to get out of the stomach than a glass of juice.

     

    Secondary factor is the speed at which the intestinal walls extract water from the lumen; hypertonicity slows fluid absorption, small amounts of glucose and fructose stimulate it. Research on this topic goes into formulation of oral rehydration solutions, especially for athletes.
