Pls show detailed solution Example 2.2A typical industrial-scale wind turbine has a peak efficiency of about 0.44 for a wind speed of 9 m·s−1. That is, it converts about 44% of the kinetic energy of the wind approaching it into usable electrical energy. The total air flow impinging on such a turbine with a rotor diameter of 43 m is about 15,000 kg·s−1 for the given wind speed. a) How much electrical energy is produced when 1 kg of air passes through the turbine?(b) What is the power output of the turbine?(c) If there is no heat transferred to the air, and if its temperature remains unchanged, what is its change in speed upon passing through the turbine?
