A 6-MW offshore wind turbine has a capacity factor of 40%. It has a height of 120 m, and 107-m long blades. The angular acceleration is 1.17 rad/s2. Assume that the distance from the center of the turbine to the connection with the blade is negligible, and that the turbine starts from rest. At t = 12 s, calculate the velocity and the acceleration for points (a) at half the length and (b) at the tip of the blade.
A water turbine delivering 10 MW power is to be tested with the help of a
geometrically similar 1 : 10 model which runs at the same speed and efficiency.
The power developed by the model will be:
You are asked to design a small wind turbine (D-x+1.25 ft, where x is the last two digits of your student ID). Assume the wind speed is 15 mph at T-10°C and p = 0.9 bar. The efficiency of the turbine is n-
25%, meaning that 25% of the kinetic energy in the wind can be extracted. Calculate the power in watts that can be produced by your turbine. Scan the solution of the problem and upload in the vUWS before
