Question

1. Pump extracts energy from a flowing fluid. _______

2. The flow within a boundary layer can be considered inviscid flow. _______
3. Laminar boundary layer velocity profile has more mixing than the velocity profile in a turbulent boundary layer. ________
4. Flow within the log-law region is considered laminar. ________
5. In a physical modeling of air flow over a aircraft, Froude number is important._______

Answer 1

1. FALSE
2. FALSE
3. FALSE
4. FALSE
5. FALSE

Step-by-step explanation:

1) Pump does not extract energy from a flowing fluid instead is converts mechanical energy to fluid energy ( i.e. initial statement is FALSE )

2) Flow within a boundary layer cannot be considered an inviscid flow because flow within a boundary layer is considered a viscid flow ( i.e. initial statement is FALSE )

3) Laminar boundary layer velocity profile does not have more mixing than the velocity profile in a turbulent boundary layer because in a turbulent boundary layer the mixing of velocity profile is higher/more ( i.e. initial statement is FALSE )

4 ) Flow within the log-law region is considered Turbulent and not Laminar( i.e. initial statement is FALSE )

5) In a physical modeling of air flow over an aircraft the Reynold number is more important than the Froude number ( i.e. initial statement is FALSE )
