nonviscous
Not thick, runny
Nonviscous describes a fluid that flows freely without significant internal resistance—the opposite of thick or syrupy.
Water is relatively nonviscous compared to honey or motor oil.
The term appears in physics and engineering contexts: The equation assumes a nonviscous fluid.
In everyday use, thin or runny are more common.
