1. Write the differences between (a) steady and unsteady flow (b) uniform and non-uniform flow (c) laminar and turbulent flow (d) rotational and irrotational flow.

2. If for a 2-D potential flow, the velocity potential is given by φ = 4x(3y – 4), determine the velocity at point (2, 3). Determine also the value of stream function Ψ at this point.
