Flow velocity

A vector quantity is a physical measurement that has both magnitude and direction, distinguishing it from scalar quantities which have only magnitude. Vectors are crucial in fields like physics and engineering to describe quantities such as force, velocity, and displacement, and are typically represented graphically by arrows or mathematically by ordered pairs or triplets.

Energy losses refer to the reduction in the usable energy output of a system due to inefficiencies, often manifesting as heat, sound, or other forms of non-useful energy. Minimizing energy losses is crucial for improving the efficiency of systems and reducing operational costs and environmental impact.
