The following are the variables in our equations: m = mass (kg) v = wind speed (meters/second) A = rotor swept area r = radius (meters) KE = kinetic energy P = power = density = mass flow rate (kg/second) With our variables defined, let's now jump into our equations. Kinetic energy we define as: While power is KE per unit of .
Get PriceIn physics, you can calculate power based on force and speed. Because work equals force times distance, you can write the equation for power the following way, assuming that the force acts along the direction of travel: where s is the distance traveled. However, the object's speed, v, is just s divided by t, so the equation breaks down to.
