An adventurer builds a 1.80 m3 raft made out of cherry wood (PCHERRY = 800 kg/m³) and places it in the seawater (PSEAWATER = 1030 kg/m³). Determine the volume of the Styrofoam (PSTYROFOAM = 32.0 kg/m³) that would have to be attached to the bottom of the raft so only half of the raft's volume is submerged in the water. O 0.498 m3 O 0.721 m3 O 0.699 m O 0.514 m3 O 0.0072 m3
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.
