WebThe mass flow rate through an orifice is a func-tion of three basic parameters. Q (flow) is a function of • Velocity • Density • Orifice Area The reason for the mass flow rate limitation is the fixed inlet density combined with the fixed velocity. The flow charts on pages 20-22 show the choked mass flow effect for vacuum con-ditions. WebThis Air flow calculator is based on the flow through an orifice in a common application where an orifice restrictor is supplied via a regulated pressure supply and vents to atmosphere.

WebThe answer is right. Intuitively, if you want to double the velocity of the escaping air, you need to quadruple the pressure. The reason is that pressure (force) is momentum (of the air) per unit time, and if the velocity doubles, you're doubling the momentum of each parcel of air, and you're doubling the number of parcels of air. – Mike ... WebIn the second part of the experiment, compressible gas flow through an orifice was studied. An orifice is an obstruction meter used to determine the flow rate of a fluid. At the orifice, the diameter decreases to a minimum, so the velocity of the fluid reaches a maximum and the pressure reaches a minimum.
