On dry land, an athlete weighs 67.2 kg. The same athlete, when submerged in a swimming pool and hanging from a scale, has an "apparent weight" of 2.50 kg Assume that when submerged, the athlete's body contains a residual volume VR = 1.3 × 10-³ m³ of air (mainly in the lungs). Taking V – VR to be the actual volume of the athlete's body, find the body's specific gravity, SG. Express your answer using three significant figures. ? SG = Submit Request Answer Part C Determine the athlete's percent body fat assuming it is given by the formula f = ((495/SG) – 450) % ?

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.
