Example embodiments of the present invention generally relate to methods and devices for determining a hydrostatic weight of a body.
The hydrostatic weight of any object/subject may be determined by fully immersing the object/subject in a body of the liquid of known density.
Some example embodiments of the present invention include a device and method of self-determining the hydrostatic weight of a body. In some embodiments, the device and/or method may include submerging a device fully in a liquid of known density, pulling the device—perpendicular to surface of the liquid—towards the body until neutral buoyancy is attained (buoyant force exactly equal to force of gravity), and, at that moment marking the depth of the device's submersion by sealing the column of liquid of known density with a finger to “read” the depth of the Buoyometer submersion that was necessary to attain neutral buoyancy.
Having thus described the invention in general terms, reference will now be made to the accompanying drawings, which are not necessarily drawn to scale, and wherein:
A hydrostatic weighing device and a method of use are provided. The invention prototype comprises a sealed container (“float tube”) containing a known volume of air and an unsealed open-ended tube (“gauge tube”) physically attached to the “float tube” (generally as long as float tube and generally parallel). The combined device (“float tube” and “gauge tube”) is hereinafter named the Buoyometer [
The “gauge tube” is used to measure the immersion depth of the “float tube” in the fluid of known density.
The hydrostatic weight of any object/subject denser than the liquid of known density (generally water) is determined by fully immersing the object/subject in a body of the liquid of known density (generally water) [
This device and method can be used to determine the hydrostatic weight of ANY object fully submerged in any liquid of known density. For subjects that are less dense than water, this device may be utilized in conjunction with underwater weights of known density. That is, the subject would physically attach to himself/herself/itself an item of known underwater (hydrostatic) weight. By adding items of known underwater weight until totally submerged, the method of determining underwater weight (even negative underwater weight—that is, buoyancy) can be determined as described above.
For increased accuracy, the “float tube” would be narrower and/or floats of known volume could be used to buoy the subject during measurement. For example, if a subject weighed between 5.1 and 6.0 pounds underwater, a known volume float equivalent to 5.0 lbs buoyancy could be attached to the subject and the subject could use a relatively smaller diameter tubular “float tube” to determine exactly the hydrostatic weight. The relatively narrower “float tube” would increase accuracy.
This application claims priority to U.S. provisional Patent Application No. 62/987,305, filed Mar. 9, 2020, entitled “Buoyometer”, which is hereby incorporated by reference in its entirety.
