Question

Can you please attempt question 1 please. 

2.
1. Find the compressible Cp_min and lift coefficient for the subsonic and transonic aerofoils using
the data provided in Tables 1, 2 and 4. Use 2 compressibility corrections of your choice; which
one is more accurate and why?
Determine the critical Mach number and the drag-divergence Mach number for the subsonic
and transonic aerofoils, using any method you prefer. Compare the values between the two
aerofoils and explain whether the transonic aerofoil is better than the subsonic one and why.
