Question 1.
What is a velocity field?
Show hintHide hint
It describes how fluid speeds vary.
Question 2.
Define acceleration in fluid dynamics.
Show hintHide hint
Think of how fast the velocity is changing.
3Question 3.
What is the definition of a velocity field?
- Representation of constant velocity
- Variation of fluid velocity across space
- A fixed volume in fluid dynamics
Show hintHide hint
Think about how speed measurements can differ.
4Question 4.
In steady flow, components dependent on time are:
- True
- False
Show hintHide hint
Consider stability in flow parameters!
Question 5.
A cylindrical pipe narrows from a diameter of 10 cm to 5 cm. If the fluid shows a velocity of 1 m/s at the larger diameter, calculate the velocity at the smaller diameter using continuity equations.
Show hintHide hint
Consider how area affects velocity in fluid flow.
Question 6.
Discuss how fluid dynamics equations can predict pressure drop in a nozzle and the factors contributing to it.
Show hintHide hint
Connect pressure with kinetic energy in fluids.
