Different Calculations of blade To calculate the blade width we used Bitz Law.

Blade width= Betz limit x blade length BW = Betz limit x BL Where, Betz limit = 0.59 Blade length= given

Muhammad Imran Khan

Lift forceLift=1/2 x (air density) x (wind speed) 2 x (Surface area) x (lift coefficient)

where Lift coefficient= pi x angle of wind in radians Air density= = P / R.T

Muhammad Imran Khan

Drag forceFD = 1/2 x x u2 x CD x A Where, FD is the drag force is the density of the air u is the velocity of the blades relative to the air A is the reference area/surface area CD is the drag coefficient

Muhammad Imran Khan

Blade surface areaArc area = (P / 360) x x r2 Where, P= angle of arc r= radius of arc Area of rectangle = L x W Surface Area of blade = arc area + area of rectangle
