Consider a constant pressure boundary layer over a flat plate of length $L = 3\text{ m}$. The freestream velocity is $U = 60\text{ m/s}$ and the density and viscosity of the fluid respectively are $\rho = 1.23\text{ kg/m}^3$ and $\mu = 1.79 \times 10^{-5}\text{ Ns/m}^2$. Transition occurs at a distance $x_{cr} = 0.1\text{ m}$ from the leading edge. If the freestream velocity is changed to $120\text{ m/s}$, $x_{cr}$ becomes
- A. $0.2\text{ m}$
- B. $0.1\text{ m}$
- C. $0.05\text{ m}$
- D. $0.005\text{ m}$
