Question 1.
What is radial velocity?
Show hintHide hint
Think about how fluid moves away from a source.
Question 2.
Define tangential velocity.
Show hintHide hint
Consider circular motion; how does the fluid move?
3Question 3.
What is the primary characteristic of radial velocity?
- It moves outward
- It moves inward
- It is always zero
Show hintHide hint
Think about how water sprays from a garden hose.
4Question 4.
True or False: In steady flow, acceleration can be influenced by time.
- True
- False
Show hintHide hint
Reflect on what we know steady flow means.
Question 5.
A fluid with an initial velocity of 12 ft/s enters a converging nozzle where the cross-sectional area is reduced. If the velocity at the exit is recorded as 36 ft/s, calculate the acceleration.
Show hintHide hint
How can you break this down into simpler components?
Question 6.
In a steady flow through a circular pipe, the diameter at entry is 2m, and at exit is 1m. If the fluid flows at 5 m/s at entrance, determine the exit velocity and acceleration.

Remember to consider area and how it relates to velocity changes!
