Mercury is used in blood pressure apparatus for its density and stable liquid state under a range of temperatures, allowing for accurate measurement. However, due to environmental and health concerns associated with mercury, digital or aneroid blood pressure monitors are now more commonly used.
The absolute pressure in the apparatus can be calculated by converting the barometer reading to kPa, which is 97.3 kPa. The equivalent pressure in the apparatus is then 97.3 kPa - 10 kPa = 87.3 kPa.
The apparatus used in Linds method is a crucible and lid, which are used to heat a sample to high temperatures in order to determine the moisture and volatile content.
In pharmacology, an apparatus refers to a device or equipment used in experimental studies or testing, such as a spectrophotometer or chromatography system. Apparatus are essential tools for conducting research and analyzing pharmaceutical compounds.

The parts of this apparatus include the bladder, aneroid gauge, tubing, and ear piece.
It is equipment to measure blood pressure called a sphigmomanometer.

i think mercury has high value density and its density depend on temperature for small size volumes, it is suitable (little change of mercury volume result significant mass value & easy Measurable) saeedhoseini
To make the measuring apparatus a managable size i.e approx 10 inches high for Mercury tube. If water was used the tube would need to be much larger and the apparatus would be unmanageable when being carried around.
A barometer is the apparatus used for measuring atmospheric pressure. It works by balancing the weight of the atmosphere against a column of mercury or other fluid, which in turn reflects the pressure of the air above it.
