Witrynathe flow in a thick-Edged orifice. Moreover, when the thickness of the orifice is greater than 1.4 times the diameter of the orifice, the head loss due to friction in the orifice is also taken into account because it becomes significant. The head loss by friction in the inlet and outlet piping is not taken into account in this component. WitrynaEdit. The orifice equation describes the rate of flow of liquid through an orifice. The equation can be represented as: where Q = flow (cubic metres per second) = … WitrynaBernoulli's Equation. Bernoulli's equation is a special case of the general energy equation that is probably the most widely-used tool for solving fluid flow problems. It provides an easy way to relate the elevation head, velocity head, and pressure head of a fluid. It is possible to modify Bernoulli's equation in a manner that accounts for head … is britney getting divorced
