Flow in the boundary layer is sensitive to pressure, speed, characteristic length and kinematic viscosity. Reynolds number Re

 

Flow in the boundary layer is sensitive to pressure, speed, characteristic length and kinematic viscosity. Reynolds number Re is a single dimensionless number that represents the dependency of flow on the above-mentioned parameters. Using formula provided below find Reynolds Number \[ R e=\frac{\rho v l}{\mu} \] with given data: \[ \begin{array}{l} \rho=1.4 \mathrm{~kg} / \mathrm{m} 3 \\ v=40 \mathrm{~m} / \mathrm{s} \\ l=220 \mathrm{~mm} \\ \mathrm{~T}=275 \mathrm{~K} \\ \mathrm{P}=98455 \mathrm{hPa} \end{array} \]
