How does an anemometer measure air velocity? - TimesMojo

A cup anemometer uses two 5 -cm-diameter hollow hemispheres connected to 15 -cm rods, as in Fig. P7.91. Rod drag is negligible, and the central bearing has a retarding torque of 0.004 N ·m . Making simplifying assumptions to average out the time-varying geometry, estimate and plot the variation of anemometer rotation rate Ωwith wind velocity U in the range 0<U<25 m / s for sea-level standard air. | Numerade
