Show hintHide hint
Think about what conditions are needed for energy conservation to apply.
Question 2.
What does the hydraulic grade line represent?
Show hintHide hint
Consider the energy components that contribute to HGL.
3Question 3.
What does Bernoulli's equation represent?
- Conservation of mass
- Conservation of energy
- Conservation of momentum
Show hintHide hint
Remember the key concept of energy in a flowing fluid.
4Question 4.
True or False: Bernoulli’s equation applies across different streamlines.
- True
- False
Show hintHide hint
Recall the definition and conditions that define streamline flow.
Question 5.
A horizontal pipe has a diameter of 0.5 m at point A and 0.2 m at point B. If the fluid is water at a pressure of 50 kPa at A, find the pressure at point B assuming no height differences.
Show hintHide hint
Use A1V1 = A2V2 for the velocities and substitute into Bernoulli's equation.
Question 6.
Water flows from a tank through a pipe with a valve. The height of the water tank is 10 m; find the velocity of water at the exit of the valve, assuming atmospheric pressure at the exit.
Show hintHide hint
Why does the tank height matter for the exit velocity?
