How to calculate flow rate from given stream function

WebThe stream function y = y tan-1 () + y tan-- (%) is associated with the flow field illustrated at right. It represents a long perforated pipe discharging liquid at a volumetric flow rate of 4rty (per unit length) at a heighth above a rigid wall. Find the fluid velocity. Find the pressure at the wall. Evaluate the total pressure force on the wall. The stream function is defined for incompressible (divergence-free) flows in two dimensions – as well as in three dimensions with axisymmetry. The flow velocity components can be expressed as the derivatives of the scalar stream function. The stream function can be used to plot streamlines, which represent … See more Definitions Lamb and Batchelor define the stream function $${\displaystyle \psi (x,y,t)}$$ for an incompressible flow velocity field $${\displaystyle (u(t),v(t))}$$ as follows.
