The dimensionless quantity V 2 /gL is called the Froude number F, where V is the mean velocity of flow and L is a characteristic length. The Froude number is computed by depth rather than by hydraulic radius. In open channel flow where the boundaries are irregular, the mean depth or hydraulic depth represents L, i.e., the area of flow normal to the mean velocity divided by the width of the. formula weight, in chemistry, a quantity computed by multiplying the atomic weight (in atomic mass units) of each element in a formula by the number of atoms of that element present in the formula, and then adding all of these products together. For example, the formula weight of water (H 2 O) is two times the atomic weight of hydrogen plus one.

Mass per volume 2 An element is the simplest type of substance: one that is made up of identical atoms, such as hydrogen. Once a different type of atom is combined with the atoms in an element, a compound is created; like when oxygen is combined with hydrogen and water is formed. However, if the atoms themselves don't bond but two different substances exist together, we can call them a mixture, such as water.
