Moment about Quarter Chord Point of Constant Chord Wing In order to calculate the moment about the quarter chord point per unit span of a constant chord wing placed in a lowspeed wind tunnel. 

We must first have the value of the Wing Chord length (c) in meters.
We must also have the Flow velocity in the test section in meter/second.
The Angle of Attack of the Airfoil and the Lift Coefficient corresponding to that given AOA.
Also, the Value of the Moment Coefficient about the quarterchord point is also required for the given angle of attack.
The value of meu = 1.789e5 kg/ms is taken. The value of the Reynold's Number is entered.


Performing the calculation gives, Moment about the quarterchord point per unit span. The formula used for Moment is M, c/4 = qSCm,c/4c q = Dynamic Pressure, S = Wing Area, c= Chord, M= Moment.
