Question 1.
What is steady flow?
Show hintHide hint
Think about a hose.
Question 2.
What does a control volume represent?
Show hintHide hint
Consider where you would analyze flow rates.
3Question 3.
What characterizes steady flow in fluids?
- Velocity changes over time
- Pressure remains constant
- Velocity and pressure remain constant
Show hintHide hint
Visualize the flow in a pipe with constant conditions.
4Question 4.
True or False: A control volume can vary in size and shape.
- True
- False
Show hintHide hint
Remember, control volumes are flexible based on the flow.
Question 5.
A fluid flows through a pipe with varying diameters and experiences a hydraulic jump. Determine the pressures before and after the jump given the inflow and outflow velocities.
Show hintHide hint
Use conservation of mass equations effectively!
Question 6.
Consider a nozzle that accelerates water from a tank at rest, determine the momentum change as water exits the nozzle.
Show hintHide hint
Utilize the flow rates and velocity to determine momentum influence.
