1.122 Froude number
Fr mean velocity divided by the square root of the product of the hydraulic mean depth and the acceleration due to gravity:
where
is the mean velocity of the liquid;
g is the acceleration due to gravity;
Dm is the hydraulic mean depth of the cross section
NOTE The Froude number is dimensionless.
1.122 Froudovo číslo
Fr průměrná profilová rychlost dělená druhou odmocninou součinu průměrné hloubky a gravitačního zrychlení:
kde je
průměrná profilová rychlost kapaliny;
g tíhové zrychlení;
Dm průměrná hloubka průtočného profilu.
POZNÁMKA Froudovo číslo je bezrozměrné.
