Welcome you all to my channel "Electrical Urja". In this video, I clearly explain , Which blade fan is efficient ? 1] Effect of number of blades on air flow 2] Why 1 blade or 2 blade fan is not efficient? 3] Application of 4 blade and more number fan blades 4] Why 3 blade fan is most popular #electrical #electricalengineering #fan #fanefficiency #efficientfan #3blade #4blade #electricalinterview #interview #ceilingfan #engineer
