Bernoulli's principle states
Ans. (a) Sum of kinetic energy of flow and pressure energy is constantRef: Ganong, 25th ed/p.571Velocity of blood flow (kinetic energy) and the pressure (potential energy) are interrelated by the Bernoulli's principleBernoulli's principle#States that "The sum of the kinetic energy of flow and the potential energy--is constant"#According to the principle, the greater the velocity of flow in a vessel, the lower the#lateral pressure distending its walls to keep the total energy of the system constant
