Assume a water strider has a roughly circular foot of radius 0.0204 mm. The surface tension of water is 0.0700 N/m. A.)What is the maximum possible upward force on the foot due to surface tension of the water? b.)What is the maximum mass of this water strider so that it can keep from breaking through the water surface? The strider has six legs. ?mg
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.
