 Pascal's Law Pascal's law or the principle of transmission of fluidpressure
 Control Volume Control volume is a mathematical abstraction employed in the process of creating mathematical models of physical processes.
 Volumetric Flow Rate volumetric flow rate (V ) of a system is a measure of the volume of fluid passing a point in the system per unit time.
