1.The wind turbine gives the following data: Blade length, 1 = 52 m, Wind speed, V= 12 m/s, Air density, wind and power available in the rotor. = 1.23 kg/m³, Power Coefficient, C,= 0.4, Calculate the power in the 2.A Site evaluated for a wind farm is observed to have steady winds at a speed of 8.5m/s. Determine the wind energy (a) per unit mass, (b) For a mass of 10 kg and (c) For a flow rate of 1154 kg/s of air. 3.The nominal power of the wind turbine is 3MW at wind speed 11.5m/s, generator efficiency is 94%, gear box efficiency is 0.75, power coefficient of blades is 0.59. What would be the diameter of the rotor?

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 closing the vUWS or moving to other question. DO NOT EMAIL TO LECTURER. x=08

Please answer this NEATLY, COMPLETELY, and CORRECTLY for an UPVOTE. 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.
