Mercury is a pollutant that is often associated with the combustion of coal during the generation of electricity. In what form does mercury exist when it is produced during the combustion of coal? What are some of the ways in which mercury may be...
A mercury barometer with an index which slides on the tube to memorise position of height of the column suffers from scratching and dirt. A parallel support carrying a pointer overcomes this problem. The barometer comprises a tube (2) with a reservoir (3) contg. mercury attached to a ...
Barometer:The barometer is the instrument that is used to measure the pressure. It is an inverted glass tube in which mercury is used as the liquid. The barometer is also known as the Torricellian barometer as it is invented by Evangelista Torricelli....
In summary, the horizontal pipe with varying cross-sectional areas and a flow rate of 6,00 L/s has a difference in height between the mercury columns in the U-shaped tube of 0.127 m. Using Bernoulli's principle and accounting for the change in velocity, the correct velocity of the flow...
A barometer is filled with a cylindrical column of mercury that is 79.9 cm high and 1.37 cm in diameter. If the density of mercury is 13.53 g/cm 3 , what is the mass of mercury in the column? Note that the formula for the volume of a cylinder is v = r...

The mercury barometer with automatic gravity and temperature correction and digital read-out consists of conventional mercury column barometer with analogue scale. The base of the reservoir is fitted with an ultrasonic transducer (3) so that the height of the meniscus may be determined. Temp. ...
