A two-dimensional, incompressible fluid flow is described by the stream function Ψ = xy3 m2/s on the Cartesian x-y plane. If the density and dynamic viscosity of the fluid are 1 kg/m3 and 0.1 kg/m-s, respectively, the magnitude of the pressure gradient in the x-direction at x = 1 m and y = 1 m is _______ N/m3 (round off to 1 decimal place).
Correct : 3.5 to 3.7 or 2.3 to 2.5
