Question

1. Pump extracts energy from a flowing fluid. _______

Answer 1

Answer:

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

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 )
