WebJan 3, 2024 · Bernoulli's equation has to be applied to the flow as a whole. It can't be applied to individual parts of the flow. If you split the flow into two subflows, the total of all the energies of the two subflows will be equal to that of the original flow. Since the tube is horizontal, we can ignore gravitational potential energy. Thus we have that As the incompressible steady-flow fluid passes through the orifice, pressure builds up due to flow restriction, causing the fluid velocity to increase according to Bernoulli’s equation.
