Bernoulli’s theorem is important in the field of the flow of liquids. Bernoulli’s principle can be summarized as ‘total pressure is constant everywhere in the fluid flow’. For a streamline fluid flow, the sum of the pressure (P), the kinetic energy per unit volume (ρv2/2) and the potential energy per unit volume (ρgh) remain constant.
