A container of water that has a depth of of 40 cm is sitting on a table. A toy turtle is supended from a spring scale first in the air, thenin container of water. The spring scale reading in the air i 17.8 N and the spring scale when the turtle is completley submerged in the water is 16.2 N. The density of water is 1000 kg/m^3. Assume atmospheric pressure is 1.1 * 10^5 n/m^2. Calculate the pressure at the bottom of the cotnianer before the turtle is submerged. determine how much force the water exerts on the turtle calcualte the volume of the turtle
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.
