Show hintHide hint
Think about the relationship between mass and how fast it is moving.
Question 2.
What does Bernoulli's equation allow us to calculate?
Show hintHide hint
Recall the components in Bernoulli's equation.
3Question 3.
What does the momentum equation relate to in fluid dynamics?
- Mass flow rate
- Pressure drop
- Forces acting on fluid
Show hintHide hint
Consider the forces acting during fluid motion.
4Question 4.
Bernoulli's equation is valid under which of the following assumptions?
- True
- False
Show hintHide hint
Recall the conditions for Bernoulli's principle.
Question 5.
Design a control volume around a pipe junction where fluids are mixing. Analyze the forces acting on the junction using momentum equations and calculate the equilibrium forces.
Show hintHide hint
Make sure to account for velocities and cross-sectional areas at the junction.
Question 6.
In a large water tank with an outlet at the bottom, derive the momentum equation to determine the force on the tank due to the exiting water.
Show hintHide hint
Use Bernoulli's equation to express the velocity in terms of the height of water.
