Question 3 1 pts Similitude Air flows through a 10 inch diameter circular duct at 30 ft/s. If a similar test is performed with water moving at 10 ft/s, what diameter pipe (in inches) would be needed to maintain the same dynamic characteristics? Both fluids are at standard temperature and pressure and you may assume the air is an ideal fluid. Hint: What dimensionless number do we use all the time for pipes?

Step 1

This is a problem of similitude, which implies that a relevant dimensionless number should be kept constant between the two systems. The hint suggests using a dimensionless number commonly used for pipes. This dimensionless number is the Reynolds number, which is Show more…
