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.
