16.22 Shown in Fig. 16.20 is a small decorative wheel fitted with  flat paddles so the wheel turns about its axis when acted  on by a blown stream of air. Assuming that all the air in a  15-mm-diameter stream moving at 0.35 m/s strikes one  paddle and is deflected by it at right angles, compute the  force exerted on the wheel initially when it is stationary.  The air has a density of 1.20 kg/m 3
