Hydrostatic equilibrium is used to measure the weight and density of substances using a hydrostatic balance, which compares the weight of an object in air and water. This technology can detect impurities and is used in fields such as gemology and astrophysics. Modern devices use electronic sensing and offer precision readouts and unit conversions.
If a person wanted to know how much gold or other less precious metals are in a crown, as Archimedes famously did, it would be necessary to understand the principle of hydrostatic equilibrium, or hydrostatic equilibrium; this can be accomplished with the help of laboratory equipment that shares the name: a hydrostatic balance. Essentially, this device measures the weight of a substance or object, such as a gemstone or a fluid. It does this by comparing the weight of the object suspended in the air and still in the water, where, as swimmers know, objects appear to be much lighter; this is due to the upward push that water exerts on an object, which can also displace water from its container. The equipment that measures these characteristics often resembles a mechanical or electronic scale with a vessel attached to hold the substance in question.
To determine density characteristics using a hydrostatic balance, a substance is first weighed in air, then the same substance is placed in a larger vessel containing water. These two measurements are compared and formulated to describe the gravity of the substance. Measuring gravity provides researchers with vital information about object density or how a substance or object will behave under varying pressures.
Hydrostatic equilibrium often refers to the relationship between gravity and gas pressure on a substance. Substances experience different amounts of pressure at different depths. The deeper the area, the more pressure it experiences from gravity. Essentially, when gravity presses down – a relative increase – the pressure gradient of the substance also increases. Simply put, to measure the gold in a crown, it can help to know that the upward force of water on an object is equal to the weight of its displaced fluid.
These forces can interact with a substance in other aspects, such as temperature and surface area, generating pressures or energy. The hydrostatic balance can suspend elements in other mixtures than water, to measure the gravity of substances. Measurements can also detect the purity of substances that may be mixed with other items; for example, if a crown contains impurities, or in the case of Archimedes, silver, which has a measurably different hydrostatic equilibrium from gold. Today the technology is used in applications such as gemology, astrophysics, geology and the atmosphere; on larger scales, the principle is used to describe the characteristics of planets and stars. In all of these contexts, hydrostatic equilibrium refers to how a substance may behave or maintain its shape or composition under varying pressures.
Traditionally, hydrostatic balance technology relied on mechanical equipment. This technology was typically modeled as a balance joint: a T-shaped structure that supported two plates at either end. Differences in weight would cause the balance wheel to lean towards the heavier element.
Modern hydrostatic balancing equipment is based on accurate electronic sensing. The technology can resemble a scale with a single vessel suspended from an electronic platform. Tools can be scaled to various sizes; some are designed for bench operation, while others are larger, standalone equipment to handle larger vessels.
Modern devices offer digital outputs and numerous other precision readouts. Computerized digital sensors can report not only the given hydrostatic balance of a feature, but can also provide additional calculated information. Such data may include running analyzes and comparisons between measurement series, as well as unit conversions between imperial or metric systems; for prompt production in any required size.
