The height of the barometer that is required to measure the standard sea level pressure if the barometer is built using mercury.
Answer to Problem 1GST
Explanation of Solution
Given info:
The density of the mercury is 13.5 times heavier than water.
Density is given as the ratio of the mass to the volume and the volume is the product of area and height.
Express the relation for density.
Hence, the density is inversely proportional to the height
The average sea-level pressure in the normal mercury barometer is recorded at 29.94 inches on the mercury barometer.
The expression for calculating the height of barometer with water is as follows:
Substitute
Conclusion:
The height of the barometer that is required to measure the standard sea level pressure if the barometer is built using mercury is
