Velocity The theoretical velocity may be calculated by writing Bernoulli's equation for points 1 and 2Thus V2 2gh The coefficient of contraction Cc is the ratio.
Equation 11 CONSERVATION OF MASS When a fluid flows at a constant rate in a pipe or duct the mass flow.
An Orifice is a small opening of cross-section that is present on the side at the bottom of the tank A mouthpiece is a short length of a pipe which is 2-3 times its diameter in length and is fitted in a tank or vessel that contains the fluid.
Plug in a coefficient for energy losses through turbulence and you have your formula But you can see indeed that your coefficient can never be greater than one because that would mean that you end up with more energy than you started with.
