Awind turbine system has the following specifications: diameter: 45 m rated power 700 kw at the wind speed of 12 m/s turbine speed 1500 rpm determine the swept area of the wind turbine. a)- 1640 m^2 b)- 1690 m^2 c)- 1590 m^2 d)- 1540 m^2

What precautions should you take to prevent injuries when dealing with heavy loads?

Determine whether or not it is possible to compress air adiabatically from k to 140 kpa and 400 k. what is the entropy change during this process?

Consider a large isothermal enclosure that is maintained at a uniform temperature of 2000 k. calculate the emissive power of the radiation that emerges from a small aperture on the enclosure surface. what is the wavelength ? , below which 10% of the emission is concentrated? what is the wavelength ? 2 above which 10% of the emission is concentrated? determine the wavelength at which maximum spectral emissive power occurs. what is the irradiation incident on a small object placed inside the enclosure?
