The hydrometer sinks deeper in low-density liquids such as kerosene, gasoline, and alcohol, and less deep in high-density liquids such as brine, milk, and acids. It is usual for hydrometers to be used with dense liquids to have the mark 1.000 (for water) near the top of the stem, and those for use with lighter liquids to have 1.000 near the bottom.
The Fahrenheit hydrometer is a device used to measure the density of a liquid. It was invented by Daniel Gabriel Fahrenheit (1686–1736), better known for his work in thermometry . The Nicholson hydrometer , after William Nicholson (1753-1815), is similar in design, but instead of a weighted bulb at the bottom there is a small container ...
The Agua del Toro Dam is an arch dam on the Diamante River about 63 kilometres (39 mi) west of San Rafael in Mendoza Province, Argentina. The primary purpose of the dam is hydroelectric power generation and it supports a 150 megawatts (200,000 hp) power station located downstream. Construction on the dam began in 1966, and it was completed in 1973.
Hydrometry is the monitoring of the components of the hydrological cycle including rainfall, groundwater characteristics, as well as water quality and flow characteristics of surface waters. [1]
Another type of hydrometer is the electronic Oscillating Body hydrometer which determines the density of a small sample drawn into a glass tube mounted on an oscillating mechanism. The difference in frequency between the test sample and a reference sample of distilled water is a measure of the density of the sample, which is displayed digitally.
El Parterre is a landscaped park in Aguadilla, Puerto Rico, that was built in 1851.The park encloses the Ojo de Agua (lit. ' water eye ', Spanish for 'spring' or 'water source'), also referred to as Manantial Ojo de Agua, [2] a natural spring which was a source of water for Spanish soldiers, and the source of a small rivulet locally called Chico River ('little river') which empties into the ...
