(II) On dry land, an athlete weighs 70.2 kg. The same athlete, when submerged in a swimming pool and hanging from a scale, has an "apparent weight" of 3.4 kg. Using Example 10-8 as a guide, (a) find the total volume V of the submerged athlete. (b) 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 – Vg to be the actual volume of the athlete's body, find the body's specific gravity, SG. (c) What is the athlete's percent body fat assuming it is given by the formula (495/SG) – 450? | lift
