"The Relationship between Fluid Pressure and Flow Velocity" Pressure PPT Courseware 5
teaching objectives
1. Knowledge and skills
Understand the relationship between fluid pressure and flow rate.
Understand how lift is generated in an airplane.
Understand the phenomena related to the pressure and flow rate of fluids in daily life.
2. Process and methods
Through observation, understand the phenomenon related to gas pressure and flow rate.
Experience the force created by differences in gas pressure.
3. Emotions, attitudes and values
Gain a preliminary understanding of the mysteries of phenomena caused by differences in gas pressure, and gain a love and affinity for science.
1. The relationship between gas pressure and flow rate
When air is blown over a coin in a direction parallel to the tabletop, the flow rate of the air above the coin is greater than the flow rate of the air below it.
If you put a small piece of paper to your mouth and blow air from above the paper, what will you see?
Place a piece of paper between two stacks of books and blow air from under the edge of the paper with a pen. What will you see when air passes under the paper?
The relationship between liquid pressure and flow rate
Ask a question:
When the liquid in the connector flows, is the liquid level still flat? Is the pressure still the same at the bottom of the container?
design experiment:
Put two small boats on the water, flush the water in the middle with a water pipe, and observe the phenomenon.
Summary
1. Fluid: Fluid liquids and gases are collectively called fluids.
2. When the fluid is flowing, the pressure is small where the flow velocity is high; the pressure is high where the flow velocity is low.
3. The lift of an airplane is generated by the pressure difference on the surface of the wing.
Consolidation exercises
1. In physics, liquids and gases with ________ are collectively called fluids. The pressure of the fluid is related to _______. The greater the ______, the smaller the pressure.
2. As shown in the figure: it is a cross-sectional view of a solar car. Judging from the shape, when this car is traveling at high speed, the pressure F1 generated on the ground is compared with the pressure F2 generated when parked on the horizontal ground ( )
A F1F2
C F1=F2 D Cannot be compared
