Question

Quastion 1:

choose the right answer for the following questions:

a) Euler’s equation arises from neglecting the …………. Terms in the more general Navier-Stokes equations.

1- Density 2- Pressure 3-Viscosity 4-None

b) A……………. is used to decelerate a flowing fluid to zero by a frictionless process, thereby allowing the measurement of stagnation pressure.

1-Static pressure probe 2-pitot tube 3-orifice plate 4-none

c) There is a flow probe that depend on 5 parameters and has 3 independent Dimensions. How many pi parameters will that flow problem have?

1-3 2-5 3-2 4-Not enough information

D) The Reynolds number compares initial to …… effect in a flow problem.

1- Pressure 2- Surface tension 3-Viscus 4- none

a. Viscosity. In Eulers equation the viscosity and thermal conductivity is taken zero.

b. Pitot tube.

c. Not enough information.

d. Viscus.
