The concept of Archimedes' principle is that an object immersed in a fluid is buoyed up by a force equal to the weight of the fluid displaced by the object. [2] The weight of the displaced fluid can be found mathematically. The mass of the displaced fluid can be expressed in terms of the density and its volume, m = ρV.
"The majority of the adult body is water, up to 60% of your weight," says Schnoll-Sussman, adding that the average person's weight can fluctuate one to five pounds per day due to water.
In Australia, this gauge is typically referred to as narrow gauge in comparison to 4 ft 8 + 1 ⁄ 2 in (1,435 mm) standard gauge or 5 ft 3 in (1,600 mm) broad gauge. In some instances, simply 3 foot 6 inch — or in rarer cases medium gauge — is used to distinguish it from other narrow gauges.
It is defined as the pressure exerted by a column of water of 1 inch in height at defined conditions. At a temperature of 4 °C (39.2 °F) pure water has its highest density (1000 kg/m 3). At that temperature and assuming the standard acceleration of gravity, 1 inAq is approximately 249.082 pascals (0.0361263 psi). [2]
