Large wind turbines with a power capacity of 8 MW and blade span diameters of over 160 m areavailable for electric power generation. Consider a wind turbine with a blade span diameter of 120m installed at a site subjected to steady winds at 8.25 m/s. Taking the overall efficiency of thewind turbine to be 33 percent and the air density to be 1.25 kg/m3, determine the electric powergenerated by this wind turbine. Also, assuming steady winds of 8.25 m/s during a 24-h period,determine the amount of electric energy and the revenue generated per day for a unit price of$0.08/kWh for electricity.
The basic barometer can be used to measure the height of a building. If the barometric readingsat the top and at the bottom of a building are 672 and 696 mmHg, respectively, determine theheight of the building. Take the densities of air and mercury to be 1.18 kg/m3 and 13,600 kg/m3,respectively
