Question 1.
Define one-dimensional flow in your own words.
Show hintHide hint
Think about how the fluid behaves in a straight pipe.
Question 2.
Write down Bernoulli's equation.
Show hintHide hint
Remember the three energy terms it relates together.
3Question 3.
What does Bernoulli's equation relate?
- Pressure and time
- Pressure
- velocity
- and height
- Only velocity
Show hintHide hint
Remember the components of energy in a fluid system.
4Question 4.
In one-dimensional flow, how do properties vary?
- True
- False
Show hintHide hint
Consider how fluids behave in pipes or ducts.
Question 5.
An open tank, 2 meters high, has a hole at 1 meter height where water flows out. If the water level drops to 1.5 meters, what is the velocity of the water exiting the hole? (Assume g = 9.81 m/s²)
Show hintHide hint
Remember to use the height difference to calculate the exit velocity.
Question 6.
A circular pipe narrows from a diameter of 1 meter to 0.5 meters. If the fluid velocity before the narrowing is 3 m/s, calculate the velocity in the narrower section.
Show hintHide hint
Use the area and velocity relationship based on the conservation of mass.
