Consider steady, incompressible, inviscid flow past two airfoils shown in the figure. The coefficient of pressure at the trailing edge of the airfoil with finite angle, shown in figure (I), is CP1 while that at the trailing edge of the airfoil with cusp, shown in figure (II), is CPH. Which one of the following options is TRUE?
A
CP1 < 1, CPH < 1
B
CP1 = 1, CPH = 1
C
CP1 = 1, CPH < 1
D
CP1 < 1, CPH = 1

Correct : d
