The average density of the human body is 985 kg/m 3, and the typical density of seawater is about 1020 kg/m 3.a) Draw a free-body diagram of a human body floating in seawater and determine what percentage of the body's volume is submerged.b) The average density of the human body, after maximum inhalation of air, changes to 945 kg/m 3.) Draw a free-body diagram of a human body floating in seawater and determine what percentage of the body's volume is submerged. b) The average density of the human body, after maximum inhalation of air, changes to 945 kg/m 3.
This is a rearrangement of the calculation of density as mass per unit volume. The term specific volume is used for volume divided by mass. This is the reciprocal of the mass density, expressed in units such as cubic meters per kilogram (mÂ³Â·kg-1). To find human mass weigh and divide by 0.001 kg/cm3. A 70 kg reference human male has a body volume of 0.06m3.
