How RDA is calculated?
The RDA is set at the EAR plus twice the standard deviation (SD) if known (RDA = EAR + 2 SD); if data about variability in requirements are insufficient to calculate an SD, a coefficient of variation for the EAR of 10 percent is ordinarily assumed (RDA = 1.2 x EAR).

Why isn’t there an RDA or ear for water?
Because EAR and RDA values could not be established for daily water intake due to the large variation in water needs across the population, the IOM panel established AI values of 3.7 L/day in males (130 oz; the equivalent of 16 cups of fluid) and 2.7 L/day for females (95 oz; about 12 cups).
