Absolute pressure of oil tank at 760 mm of mercury barometer Date of Exam May 1994 Subject Hydraulics and Geotechnical Engineering Problem A barometer reads 760 mm Hg and a pressure gage attached to a tank of oil (s = 0.8) reads 850 cm. What is the absolute pressure in the tank in kilogram per square centimeter? A. 1.71 C. 0.32 B. 2.54 D. 3.21 Answer Key Click here to show or hide the answer key [ A ] Solution Click here to expand or collapse this section $p_{abs} = p_{atm} + p_{gage}$ $p_{abs} = (1000 \times 13.6)(0.76) + (1000 \times 0.8)(8.5)$ $p_{abs} = 17136 ~ \text{kg/m}^2$ $p_{abs} = 1.71 ~ \text{kg/cm}^2$ ← answer Category Hydraulics Absolute Pressure Barometer gage pressure atmospheric pressure Log in to post comments
