In a two-dimensional vortex flow, the fluid flows in circular paths around the center of the vortex. The magnitude of the velocity decreases with distance from the center. The stream function for a two-dimensional vortex centered at the origin is ψ=ln sqrt(x^2+y^2) where the x--y plane is horizontal and x and y are in meters. Show that continuity of the flow is satisfied and determine the magnitude of the horizontal velocity at A, where x=−0.2m, y=0.4m. Express your answer in m/s to three significant figures

In the steady flow of a Newtonian fluid through a long uniform circular tube, if NRe <2100 the flow is laminar and the fluid elements move in smooth, straight, parallel lines. Under these conditions, it is known that the relation between the flow rate and the pressure drop in the pipe does not depend upon the fluid density or the pipe wall material. Perform a dimensional analysis of this system to determine the dimensionless groups that apply. Express your result...
