SOLVED: Consider the flow of air through a wind turbine whose blades sweep an area of diameter D (in m). The average air velocity through the swept area is V (in m/s). On the bases of the units of the quantities involved, show that the mass flow rate of air (in kg/s) through the swept area is proportional to air density, the wind velocity, and the square of the diameter of the swept area

A small round object is tested in a 0.75 -m diameter wind tunnel. The pressure is uniform across sections (D and (2). The upstream pressure is 30 mm H2 O (gage), the downstream pressure is 15 mm H2 O (gage), and the mean air speed is 12.5 m / s. The velocity profile at section (2) is linear; it varies from zero at the tunnel centerline to a maximum at the tunnel wall. Calculate (a) the mass flow rate in the wind tunnel, (b) the maximum velocity at section (2), and (c) the drag of the object and

The desired electrical output power of a horizontal axis wind turbine is 2.75 kW . A site has been selected where the average wind speed is 3.2 m / s. The power coefficient and combined efficiency of the turbine are 0.49 and 0.25 , respectively. Using 1.16 kg / m^3 as the density of air, find the required blade diameter of the turbine. | Numerade
