As a means of preventing ice formation on the wings of a  small,  private  aircraft, it is proposed that electric resistance heating  elements be installed within the wings. To determine representative power requirements, consider nominal flight conditions for which the plane  moves at 100 m/s in air that is at a temperature of -23°C. If the characteristic length of the airfoil is = 2 m and wind tunnel measurements indicate an average friction coefficient of Cf = 0.0025 for the nominal conditions, what is the average heat flux needed to maintain a surface temperature of Ts  = 5°C?
