Okay is the blade speed say mean speed will be the difference between the tangential component of actual inlet vel of air and relative velocity ...where as the relative vel is tangential to blade and actual vel is the floe direction of air at inlet...huh I think I am getting it thanks for the...
okay assuming no losses what might be the exit velocity how to calculate that ..I think that will depend upon the blade angle and the amount of energy transfer taking place from the air .. so can u suggest me some way to calculate the exit speed if I know the blade angle at inlet . say radial...
I want to design a wind toubine ,I know the wnd vel,I need certain amount of power ..How to design it and how to calculate at which rpm will it rotate to deliver my required power?
How far I think the inlet kinetic energy will not be completely used...say if v1 be the inlet velocity then there will be outlet vel. as u can't deaccelerate the air to a vel of zero..u mig get the energy conversion by .5m(Vin^2-Vout^2) ...now here the problem rises with what will be the outlet...
