Problem 9RQ

Why would a water barometer have to be 13.6 times taller than a mercury barometer?

Step-by-Step Solution:
Step 1 of 3

Solution 9RQ We know that pressure with height is P = hdg , h = height ,d = density , g = acceleration due to gravity The density of mercury is 13.6 g/cm and that of water is 1 g/cm . Therefore, mercury is 13.6 times denser than water. Thus, to maintain same pressure the water barometer has to be 13.6 times taller than mercury barometer.
