Use 1=162lb/ft3 for glass and 2=62.4lb/ft3 for water.An air-filled, hemispherical shell is attached to the ocean floor at adepth of 10 m as shown in fig. A mercury barometer located inside the shell reads 765 mmHg (absolute pressure inside the shell)m, and a mercury u-tube manometer designedto givethe outside water pressure indicates differential reading of 735 mmHg as illusrated. Based on these data,what is the atmospheric pressure at the ocean surface for seawater (SG=1.03)Assuming the specific weight of the air to be 12N/cu.m, what is the approximate height of Mt. Banahaw if a mercury barometer at its base reads 654mm and at the same time another mercury barometer at the top reads 480mm. what is the approximate height of Mt. Banahaw in meters?
