The velocity potential for a certain inviscid, incompressible flow field is given by the equation where φ has the units of m2/s when x and y are in meters. determine the pressure at the point x = 1.7 m, y = 1.7 m if the pressure at x = 1 m, y = 1 m is 2600 kpa. elevation changes can be neglected, and the fluid is water.
