Chapter 11.1, Problem 11.27P

Experimental data indicate that in a region downstream of a given louvered supply vent the velocity of the emitted air is defined by $v=0.10$v₀/x, where v and x are expressed in m/s and meters, respectively, and v₀is the initial discharge velocity of the air. For $v_0=3.6$ m/s, determine (a) the acceleration of the air at $x=2$ m, (b) the time required for the air to flow from $x=1$ to $x=3$ m.
