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
