The National Renewal Energy Laboratory is developing a 10 MW (10x106 W) wind turbine for off-shore installation. Assume the energy conversion efficiency is 45%. The wind speed is rated at 12 m/s. What is the minimum length of blade for this turbine?
How do I Answer this question? I don't know...
A standard 3-blade horizontal axis wind turbine is installed in an area where the average wind speed is 10 meters/second.The Length of each blade is 10 meters and the installation site is at sea level. The Energy conversion efficiency of this turbine is 40% (Betz Limit is 59.3%)
a) How many...
