stream function

A steady two-dimensional flow field is specified by the stream function ψ = kx 3 y, where x and y are in meters and the constant k = 1 m -2 s -1 . The magnitude of acceleration at...

The volume tric flow rate (per unit depth) between two streamlines having stream functions $${\psi _1}$$ & $${\psi _2}$$ is

The stream function in a two dimensional flow field is given by $$\Psi = {x^2} - {y^2}$$ The magnitude of the velocity at point $$(1,1)$$ is
