Question:

The Wide World of Fluids article "Learning from Nature,". As indicated in Fig. P9.122, birds can significantly alter their body shape and increase their planform area, \(A\), by spreading their wing and tail feathers, thereby reducing their flight speed. If during landing the planform area is increased by \(50 \%\) and the lift coefficient increased by \(30 \%\) while all other parameters are held constant, by what percent is the flight speed reduced?
