the height of a mercury barometer is 76 cm at sea level and 50 cm at the top of a hill. Determine the height of the hill. (Densities of air and mercury are 1.36kgm−3and13.6×103kgm−3) hint : Difference of
Submit The height of the mercury column in a barometer at a place is 75 cm. If a liquid of unknown density is used the height of the liquid column is 150 cm, find its density. View Solution Free Ncert Solutions English Medium NCERT Solutions ...
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. ...
The densities of mercury and corn oil are 13.5 g/ML and 0.92 g/mL, respectively. If corn oil were used in a barometer, what would be the height of the column, in meters, at standard atmospheric pressure? Calculate the height, in feet, of a column of water that would exert the same...
If a barometer were built using water instead of Hg, how high would the column of water be if the pressure were 1 atm, knowing that the density of water is 13.6 times lower than that of mercury?How high would a column of mercury ris...
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 ...

Atmospheric Pressure: The pressure in the water column is directly proportional to the height of the fluid and the density of the fluid. The atmospheric pressure is {eq}\rm 1.01325 \times 10^{5} \ Pa {/eq}, therefore, we need that much height to produce t...
How does the pressure at the bottom of a 76 cm column of mercury in a barometer. Compare with air pressure at the bottom of the atmosphere? What is the pressure due to a man weighing 80 kilograms, standing on his feet? Given the area of his feet is 16...
