(adsbygoogle = window.adsbygoogle || []).push({}); A passenger jet cruises at 525 mph and an altitude of 39,000 ft. The wing chord is 3 m. If the local density is 6.14 x 10-4sl/ft3 and the dynamic viscosity is 2.97 x 10-7lbf-s/ft2, what is the cruise Re number based on the chord? Make sure your units are consistent in your calculations!

2. Equation for Re, which I believe is Re=(pvL)/u where p=density, v=velocity, L=length, u=dynamic viscosity. We haven't been taught the equation, supposed to find it online, and I believe this is it.

3. My issue is I am confused as to what units I should keep everything in and also I have no idea what lb-s/ft2 is.
