Buoyancy, or buoyant force, is based on Archimedes' Principle. This principle states, "Any object, wholly or partly immersed in a fluid, is buoyed up by a force equal to the weight of the fluid displaced by the object." Archimides' Principle is important in hydro-engineering applications, ...
To determine the density of a solid that has regular side lengths, it is first needed to calculate the volume of the solid using the equation volume = length x width x height. Once the volume is calculated, the mass can be found on a scale and the calculation of density can be complete...
Wind force on the sails causes a sailboat to heel. Resistance to heeling, called righting moment (RM),results from the lateral movement of the boat's center of buoyancy away from the center of gravity (CG). Righting arm and righting couple...
I will then cover specific factors that determine the likely quality of a wreck diving course; the instructor, the training location and the wreck diving course structure. Don’t be under any illusions that all wreck instructors and wreck qualifications are identical. There is a wide variation be...
Engineers help ships to achieve buoyancy by choosing lightweight, sturdy materials and dispersing the weight of the ship across the hull. The hull, or body of the ship below the main deck, is typically very wide and has a deep base line, or bottom. Large ships such as freighters, naval...
There are important sizing and fit differences between an adult PFD and a child's PFD. Most notably, you use the child's weight to determine the correct size rather than using a chest measurement like you do for an adult. Children's life jackets are labeled as being for an infant, child...
Sizing a PFD for children isn’t the same as sizing a life jacket for an adult. Rather than using a chest size to determine the best fit, child PFDs are sized by weight. A child’s weight should determine whether they use an infant PFD, child PFD, or youth PFD. ...
aVIP systems measure changes between successive video image frames. Passing vehicles cause variations in the gray levels of the black-and-white pixel groups. VIP systems analyze these variations to determine vehicle passage. Variations due to non-vehicle factors, such as weather and shadows, are ex...

Buoyancy correctionGas sorptionDetermining sample volumes for gas sorption measurements by pycnometry is often considered to be trivial, as it is assumed that helium does not sorb to the sample material. The aim of this study is to show the contrary, i.e., helium may sorb to certain ...
