Web21 nov. 2024 · Thus the velocity of a fluid flowing out from an orifice can be calculated as follows: WL = Wkin m ⋅ g ⋅ h = 1 2 ⋅ m ⋅ v2d vd = √2gh Note that this formula is only valid under the condition that the liquid can flow out freely. By assuming steady-state, incompressible (constant fluid density), inviscid, laminar flow in a horizontal pipe (no change in elevation) with negligible frictional losses, Bernoulli's equation (which expresses the conservation of energy of an incompressible fluid parcel as it moves between two points on the same streamline) can be rewritten without the gravitational potential energy term and reduced to:

WebFor a vertical grate, enter the vertical spacing between the rows of openings. For a horizontal grate, you also have the option to set the overall grate dimensions. This will check for possible weir flow around the perimeter of the grate, which may restrict the flow at very low heads.

WebEquation 14-1 is valid for the venturi, nozzle, and orifice meters using proper respective effective coefficients. Each kind of flow meter has a different value of effective discharge coefficient. More details concerning what is accounted for by the effective discharge coefficient are covered in chapter 2.
