Head bernoulli equation
WebFirst, with the Bernoulli equation (that is, without a head-loss term), the theoretical velocity at the throat is obtained. Then by multiplying this by the venturi factor (Cv), which accounts for friction losses and equals 0.98 for … WebBernoulli’s equation provides the mathematical basis of Bernoulli’s Principle. It states that the total energy (total head) of fluid along a streamline always remains constant. The total energy is represented by the pressure head, velocity head, and elevation head.
