A. 815 mmHg B. 760 mmHg C. 55 mmHg Manometer: In fluid mechanics, manometers are the devices used to measure the pressure of a fluid. Different types of manometers used to measure pressure are classified as follows: Single ...
its first modern scientific applications date back to 1643 when Torricelli used it in the barometer to measure pressure and about eight decades later Fahrenheit used it in the thermometer to measure temperature. Before this, mercury’s use was confined to decorative work, gold extraction and medicin...
View Solution A barometer kept in an alevator ac celerating upward reads 76 cm of mrecury. If the elevator is ac celerating upwards at4.5ms−2find the air pressure in the elevator in cm of mercury. Density of mercuty=13.6×103kgm−3G=9.8m/s2 ...
Up to the present day mercury has not lost its importance for scientific investigation. Its liquid nature, fairly great chemical resistibility, considerable density, etc., assures its unceasing use for physico-chemical apparatus, of which the thermometer and barometer need only be mentioned as the ...
Pressure can be measured through the use of an instrument called a barometer. One of the oldest forms of a barometer is called the mercury barometer. The use of this instrument for pressure measurement is directly related to the old "mm of Hg" un...
Convert kilopascals to millimeters of mercury. kPa to mmHg to kPa, pressure converter, calculator. Formula and explanation, conversion tables.
When a force is applied perpendicular to a surface area, it exerts pressure on that surface equal to the ratio of F to A, where F is the force and A the surface area. Hence, the formula for pressure is: P = F/A One interesting consequence of this ratio is the fact that pressure...
Although mercury is known from early times and was used by alchemists, its first modern scientific applications date back to 1643 when Torricelli used it in the barometer to measure pressure and about eight decades later Fahrenheit used it in the thermometer to measure temperature. Before this, me...
