You can get more accurate data from the Electric Mountain web site but it seems to change annually. Using the figures below is ok. Height of Marchlyn Mawr above turbines approx. 450m Flow rate into each turbine approx. 75000 l/s Wind Power Data Determine the diameter of the turbine blades and subsequently calculate the radius (r). R approx.. 45m Measure the wind speed and if necessary convert it to m/s. Approx. 6m/s Determine the number of revolutions per minute (rpm) of the turbine (you will need a stop watch). Approx. 10 rpm
