Question 1.
Define stream function and its role in fluid mechanics.
Show hintHide hint
Think about how streamlines help visualize fluid paths.
Question 2.
What is a pressure gradient?
Show hintHide hint
Consider how fluid moves from high to low pressure.
3Question 3.
What does a stream function represent?
- Velocity field
- Pressure distribution
- Streamlines
Show hintHide hint
Remember it's visualizing the path of the fluid.
4Question 4.
True or False: Fluids flow from high pressure to low pressure.
- True
- False
Show hintHide hint
Think at the basic principle of fluid movement.
Question 5.
A fluid flows around a cylindrical object. If the pressure gradient on one side of the cylinder is 500 Pa/m and on the opposite side is 300 Pa/m, calculate the expected net force acting on the fluid around the cylinder.
Show hintHide hint
Remember the basic principle: Force = Pressure x Area.
Question 6.
In a complex machinery system, analyze how changes in stream functions would affect the overall energy efficiency of fluid movement.
Show hintHide hint
Consider how energy conservation applies with changing velocities.
