Question: Put the gauge at a depth of exactly 1 meter (it should read 9.8 kPa). Now change gravity to 4.9 m/s/s and then 19.6. Explain any patterns.

Put the gauge at a depth of 1 meter and set gravity back to 9.8. Change the fluid density to 700 kg/m3 and 1400 kg/m3. Explain any patterns.

Summarize the previous experiments by stating what factors affect pressure and whether the effects are direct or indirect.

Convert your written summary into an equation ( i.e. P = .....). Test your equation to predict the pressure at the bottom of the rectangular tank of seawater of density 1030. Show all of your work including units.

Create a graph showing this relationship between Pressure and Depth. Is this relationship linear? If so, what is the slope?

Turn air pressure back on. Pick the crazy looking tank with a narrow tube and wide pool. Make sure the water is plain water, on the earth. Put a pressure marker on the bottom of the tank. Drop a 250 kg mass in the hole.

Does the water exert a force on the mass? How do you know?
Did the pressure change? By how much?

Remove the mass. Put a second pressure gauge at a depth of 0.5 meters in the wide pool. Drop the mass in again. Did the pressure change? By how much? Compare this to the pressure change you found above.

What happens to the gauges if you use the 500kg mass instead?

Try dropping the 250 mass again but now observe the water carefully (ruler!) to compare the movement of water in the small tube to the movement of water in the wider pool. Why do you think these amounts are different?

Turn off atmospheric pressure. What happened? Explain your results using past observations
