Air at atmospheric pressure and at 300K flows with a velocity of 1.5m/s over a flat plate. The transition from laminar to turbulent flow is assumed to take place at a Reynolds number of 5x10'. Determine the distance from the leading edge of the plate at which transition occurs.

Respuesta :

Answer:3.47 m

Explanation:

Given

Temperature(T)=300 K

velocity(v)=1.5 m/s

At 300 K

[tex]\mu =1.846 \times 10^{-5} Pa-s[/tex]

[tex]\rho =1.77 kg/m^3[/tex]

And reynold's number is given by

[tex]Re.=\frac{\rho v\time x}{\mu }[/tex]

[tex]5\times 10^5=\frac{1.77\times 1.5\times x}{1.846\times 10^{-5}}[/tex]

[tex]x=\frac{5\times 10^5\times 1.846\times 10^{-5}}{1.77\times 1.5}[/tex]

x=3.47 m
