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. Webv = flow velocity (m/s, ft/s) The equation can be adapted to vertical flow by adding elevation heights: p1 + 1/2 ρ v12 + γ h1 = p2 + 1/2 ρ v22 + γ h2 (1b) where γ = specific weight of fluid (kg/m3, slugs/ft3) h = elevation (m, ft) … WebThe analytical model was built on the basis of the upper bound theorem utilising a general streamline equation controlled by a shape factor n, and the curvature was calculated using the material flow velocity gradient across the die exit orifice.
