Give the names of physical quantities which are needed to describe a fluid.
(N/A) To describe the state and behavior of a fluid,the primary physical quantities required are:
$1$. Pressure $(P)$: The force exerted by the fluid per unit area.
$2$. Density $(\rho)$: The mass per unit volume of the fluid.
$3$. Velocity $(v)$: The speed and direction of fluid flow (relevant for fluid dynamics).
