Find stepby-step Engineering solutions and your answer to the following textbook question: A certain flow field is described by the stream function $\phi = 2x^2y – \left(\frac23\right)y^3$ where $\phi$ has the units of m$^2$/s when x and y are in meters. Determine the pressure at the point x = 2 m, y = 2 m if the pressure at x = 1 m, y = 1 m is 200 kPa.

The negative streamlines lines are inside the solid body. The arrows are calculated by trapping the y y for given ψ ψ around the end points. . From the exact differential the flow velocity components in relation to the stream function have to be in which case they indeed satisfy the condition of zero divergence resulting from flow incompressibility, i.e. Definition by use of a vector potential The sign of the stream function depends on the definition used.
