Calculating the power of a vertical wind turbine
Height (m) x Diameter (m) x Airmass (kg/m3) 1.23 x windspeed cubed (m/s) = power in Watt
Divide by 3600 to get torque in Nm
Height 6
Diameter 1
Swept area 6
Power factor (0.5 x airmass x swept area) 3.69
5 461.25
6 797.04
7 1265.67
8 1889.28
9 2690.01
10 3690.00
11 4911.39
12 6376.32
13 8106.93
14 10125.36
15 12453.75
The effectiveness of the swept area depends on the design, so this is a high estimate,
