Root chord to radius vawt
WebAnswer: The radius of a circle with a chord is r=√(l 2 +4h 2) / 2, where 'l' is the length of the chord and 'h' is the perpendicular distance from the center of the circle to the chord. We … WebFor VAWT: A = D * H where: L is the blade length – the radius of the horizontal-axis turbine D is the diameter H is the turbine height Finding the efficiency of the turbine You can find the total efficiency of the turbine as follows: μ = (1 - kₘ) * (1 - kₑ) * (1 - ke,t) * (1 - kt) * (1 - kw) * Cₚ where: Cₚ is the turbine efficiency.
