In researching alternate energies, you find that wind power is calculated by the following equation P = Apv Where P = power [watts] A = sweep area (circular) of the blades [m2] r = air density [kg/m] V = velocity [m/s] The specific gravity of air is 0.00123 and the velocity is typically 35 meters per second. Create a graph of the theoretical power (P, in units of watts) as a function of the blade diameter (D, in units of meters). Allow the diameter to be graphed on the abscissa and vary from 0.5 to 1.5 meters.
