Power and velocity equation
Web26 Mar 2016 · vf = 0 m/s + (4.60 m/s 2 ) (5.00 s) = 23.0 m/s. Because the acceleration was constant, the average speed is. Because vi = 0 m/s, this breaks down to. Plugging in the numbers gives you the average velocity: Great — now you know the force applied and the … Web26 Jan 2010 · The formula for how to calculate power is: Where: P = Power output, kilowatts. Cp = Maximum power coefficient, ranging from 0.25 to 0.45, dimension less (theoretical maximum = 0.59) ρ = Air density, lb/ft3. A = Rotor swept area, ft2 or π D2/4 (D is the rotor diameter in ft, π = 3.1416)
