Hydrostatic Pressure: ConcepTest and Example Problem

Try to answer this ConcepTest and solve the example problem before using this module. Studies show that trying to answer the questions before studying material improves learning and retention. By the end of this module, you should be able to answer these on your own. Answers will be given at the end of this module.

A practice problem for a Hydrostatic Pressure self study module.
Example Problem 1

A mercury barometer and a water barometer are sitting side by side at the top of Mt. Elbert.  Calculate the height of fluid (in mm) in the barometers, and the ratio of height of the water to height of mercury.  Given the specific weight of mercury is 133.7 kN/m3, the specific weight of water is 9.81 kN/m3, and pressure at the summit is 57.2 kPa. Assume the vapor pressure of mercury is negligible, and the vapor pressure of water is 2.34 kPa.
