8. Shown in Figure 4.8 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/m³. (Ans: Rx = 2.6 x 10-5 N) 75 mm Section A-A Fig. 4.8 Paddle A 15-mm diam: Air stream
