I Review | Constants Learning Goal: To practice Tactics Box 14.1 Hydrostatics. pressure is determined by the gas pressure in the box. In problems about liquids in hydrostatic equilibrium, you often need to find the pressure at some point in the liquid. This Tactics Box outlines a set of rules for thinking about such hydrostatic problems. Part C Figure < 1 of 1 Assume patm = 1.00 atm. What is the gas pressure peas? Express your answer in pascals to three significant figures. • View Available Hint(s) Pgas A ? Pgas = Pa h B h2 Submit mercury 國
Fluid Pressure
The term fluid pressure is coined as, the measurement of the force per unit area of a given surface of a closed container. It is a branch of physics that helps to study the properties of fluid under various conditions of force.
Gauge Pressure
Pressure is the physical force acting per unit area on a body; the applied force is perpendicular to the surface of the object per unit area. The air around us at sea level exerts a pressure (atmospheric pressure) of about 14.7 psi but this doesn’t seem to bother anyone as the bodily fluids are constantly pushing outwards with the same force but if one swims down into the ocean a few feet below the surface one can notice the difference, there is increased pressure on the eardrum, this is due to an increase in hydrostatic pressure.
