CEE 170 Final Exam
questions with 100% correct
answers
Froude Number - answer Ratio between fluid inertial forces and fluid
gravitational forces
Inertia, pressure, and gravity forces predominate within the flow along
open channels, over dams and spillways, or the wave action on structures.
Froude number = V / sqrt(g*l)
Weber Number - answer Ratio of inertia to surface tension forces, capillary
flow
The flow of liquid films, bubble formation, and the passage
of liquids through capillarity or small-diameter tubes.
Reynolds number - answer Ratio of inertial forces to viscous forces.
Inertia, pressure, and viscous forces predominate within the flow around
cars, slow-flying airplanes, and the flow through pipes and ducts.
Reynolds number = (ρVl)/µ
Mach number - answer the ratio of an object's speed to the speed of sound
Inertia, pressure, and compressibility forces predominate within the flow
around high-speed aircraft, or the high-speed flow of gas through jet or
rocket nozzles, and through pipes.
