Water Resistant is a common mark stamped on the back of wrist watches to indicate how well a watch is sealed against the ingress of water. It is usually accompanied by an indication of the static test pressure that a sample of newly manufactured watches were exposed to in a leakage test. The test pressure can be indicated either directly in ...
Monitoring dive time by the diver. A diving watch, also commonly referred to as a diver's or dive watch, is a watch designed for underwater diving that features, as a minimum, a water resistance greater than 1.1 MPa (11 atm), the equivalent of 100 m (330 ft). The typical diver's watch will have a water resistance of around 200 to 300 m (660 to ...
Modern Vostok Amphibia classic, model 090916, manufactured 12/2018. Amfibia (often spelled "Amphibia" or "Amphibian") is a Soviet watch that in the West would be called a Dive watch. Produced in large quantities for the Soviet and Russian military, these watches gained significant popularity worldwide. The Vostok watch factory created the first ...
In heat transfer, the thermal conductivity of a substance, k, is an intensive property that indicates its ability to conduct heat. For most materials, the amount of heat conducted varies (usually non-linearly) with temperature. [ 1] Thermal conductivity is often measured with laser flash analysis. Alternative measurements are also established.
A centimetre of water [1] is a unit of pressure. It may be defined as the pressure exerted by a column of water of 1 cm in height at 4 °C (temperature of maximum density) at the standard acceleration of gravity, so that 1 cmH 2 O (4°C) = 999.9720 kg/m 3 × 9.80665 m/s 2 × 1 cm = 98.063754138 Pa ≈ 98.0638 Pa, but conventionally a nominal maximum water density of 1000 kg/m 3 is used, giving ...
Moisture vapor transmission rate ( MVTR ), also water vapor transmission rate ( WVTR ), is a measure of the passage of water vapor through a substance. It is a measure of the permeability for vapor barriers . There are many industries where moisture control is critical. Moisture sensitive foods and pharmaceuticals are put in packaging with ...
The viscosity of a fluid is a measure of its resistance to deformation at a given rate. [ 1] For liquids, it corresponds to the informal concept of "thickness": for example, syrup has a higher viscosity than water. [ 2] Viscosity is defined scientifically as a force multiplied by a time divided by an area.
Water is the chemical substance with chemical formula H 2 O; one molecule of water has two hydrogen atoms covalently bonded to a single oxygen atom. [25] Water is a tasteless, odorless liquid at ambient temperature and pressure. Liquid water has weak absorption bands at wavelengths of around 750 nm which cause it to appear to have a blue color.
