mass flow rwte intercepted by wind turbine blades is 2000*10*1.3=26000 kg/secA wind turbine has blades that sweep an area of 2000 m
2. It converts the power available in the
wind to electrical power with an efficiency of 50%.
What is the electrical power generated if the wind speed is 10 m s
–1? (The density of air is
1.3 kg m
–3.)
A
130 kW B 650 kW C 1300 kW D 2600 kW
can anyone explain this question
energy=1/2* 26000 * 100 Joules/sec or watts.
due to 50% efficiency,power produced is half of that. Divide by 1000 o express in KW
