Flow orifice symbol
WebA variable area flow meter (Figure 1) is a type of differential pressure (d/p) flow meter. Variable area flow meters are simple and versatile devices that operate at a relatively constant pressure drop and provide flow measurement of liquids, gases, and steam. The variable area flow meter is popular for industrial flow indication because it has ... WebSolve for K in terms of discharge coefficient: Many pipe flow analysis programs do not readily implement orifice discharge coefficients because they use K's instead. Hence, having a value for K based on the orifice discharge coefficient is useful for flow calculators. Symbols and units for discharge coefficient equations: A o =orifice area …
