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. Witryna30 lip 2003 · For water the basic orifice equation (in SI units)is: Q = Cd.a. (2.g.Dh)^0.5 Cd = C/ (1-C^2 (a/a1)^2)^0.5 a = area of the orifice a1 = area of the pipe Dh = head loss across the orifice C is basically the contraction coefficient (the diameter of the vena contracta/ the diameter of the orifice). WitrynaFlow Through Weirs and Orifices • For orifices, predicted outlet velocity and flow rate for frictionless flow are: ¾H is height above center of orifice, A is orifice area • In both orifices and weirs, to account for frictional losses, equations are typically written as: ¾C often ~0.6 vgH= 2 QA gH= 2 vC gH= 2 QCA gH= 2 Common Types of Weirs top ten softball players
