The title of the Project: Hydrostatic pressure

Purpose of the work:

• Identify what the hydrostatic pressure depends on.

Practical part

Choose the first window to start the experiment. 

This is a little instruction to the virtual experiment.

Part 1. Height

Virtual experiment.

Step 1. Place manometer at the bottom of the dish. Turn on the grid.

Step 2. Start pouring water into the dish until it reaches the edges. How does the pressure change as the height of the water level increases? 

Step 3. Open the tap to pour the water out of the dish. How does the pressure change as the height of the water level decreases?

Step 4. Make a conclusion.

Part 2. Density

Virtual experiment.

Step 1. Increase the density of the fluid. How does the pressure change? 

Step 2. Decrease the density of the fluid. How does the pressure change?

Step 3. Make a conclusion.

Part 3. Gravitational acceleration

Virtual experiment.

Step 1. Increase the gravitational acceleration. How does the pressure change? 

Step 2. Decrease the gravitational acceleration. How does the pressure change?

Step 3. Make a conclusion.

Conclusion

The hydrostatic pressure is directly proportional to the height of the level of fluid, the density of the fluid and the gravitational acceleration.
