4. The figure shown below represents the pressure distribution on a NACA2412 airfoil section at a = 5 degree. For a quick estimation of lift coefficient, these curves are approximated as the dotted line as shown. a. Find the estimated value of lift coefficient b. Find the estimated location of center of lift C. Find the estimate value of moment coefficient about the leading edge Cp -3.5 0.25 -3.0 -2.5 -2.0 -1.5 -1.0 0.0 0.5 0.1 -1.3 0.2 1.0 Mach0.00 Unit Re= 6.00E+006 Alpha = 5.0 Deg Total Cl 0.84682 Cd=0.00000 Cm= -0.05697 NACA 2412 Airfoil 0.8 09
