Notes for today:
Use Pascals for your unit of pressure. Remember, [Pa]=[ N
m
2 ]
For all of your pressures today, use four significant figures for your answers. For example, if the
pressure meter gives you 101.325 kPa you can write that as 101,300 Pa.
Part 1: Atmospheric Pressure
Setup
In the top right hand corner, select the grid option for the simulation.
Using the sliding knob, fill the pool so that there the water is 3 meters deep
Make sure that the acceleration due to gravity is equal to 9.8 m/s2
Click the pressure meter to control it. Drag the pressure meter to ground level and determine the pressure at
the ground. Record this value in the space below.
Patm = _____101.325_____________ Pa
This value is the atmospheric pressure; because that is the pressure you feel when one atmosphere is on top
of you.
Where do you think the atmospheric pressure is the least?
Denver, CO (1609 m above sea level) Ocean City, NJ(0 meters above sea level)
Death Valley, CA (86 meters below sea level) Hillsborough, NJ (45 meters above sea level)
Explain your response:I believe Denver Colorado has the most pressure because the abundance of mountains
and how far it is above sea level. The further away from the ground the less pressure it is.
Now let’s go under water, where the pressure is different. The pressure-meter on the simulation measures
absolute pressure, the actual pressure that is occurring. Depending on our situation it may be beneficial to
represent the pressure in a different way. Gauge pressure ignores atmospheric pressure and only takes into
