This video defines the lift coefficient, drag coefficient and moment coefficient as non-dimensional parameters for a given airfoil section using the dimensional analysis approach. The formulas for lift, drag and pitching moment acting on an airfoil as a function of air velocity, density and wing area is also discussed. The relevance of Mach number and Reynolds number in getting the airfoil lift, drag and moment coefficients is mentioned.
