QUIZ (CHAPTER 2)

Three fundamental physical principles upon which all of fluid dynamics is based on EXCEPT

• Mass is conserved

• Newton’s second law

• The Power Law

• Energy is conserved

Two main types of fluid forces are surface forces and

The total rate of change of momentum for fluid passing through a control volume consists of rate of change of momentum inside the control volume plus

• net outward velocity through boundary

• net outward mass flowrate through boundary

• net inward momentum flux through boundary

• net outward momentum flux through boundary

What is the characteristic of incompressible flow?

• mass flowrate is constant

• density is constant

• momentum is constant

• velocity is constant

Below are non-dimensional parameters in fluid mechanics EXCEPT

• Reynolds number

• Weber number

• Froude number

• Nusselt number

The rate of change of some property in a fluid element moving with the flow is called the

The conservative differential equations are so-called because they can be integrated directly to give an equivalent differentiation form involving the net change in a flux, with the flux leaving one cell equal to that entering an adjacent cell.

• TRUE

• FALSE
