The x component of velocity in an incompressible flow field is given by u = Ax, where A = 2 s-1 and the coordinates are measured in meters. The pressure at point (x, y) = (0, 0) is p0 = 190 kPa (gage). The density is rho = 1.50 kg/m3 and the z axis is vertical. (a) Evaluate the simplest possible y component of velocity. (b) Calculate the fluid acceleration and (c) determine the pressure gradient at point (x, y) = (2, 1). (d) Find the pressure distribution along the positive x axis.
