Using Specific Volume, Volume, and PressureA vacuum gage
Chapter 1, Problem 39P(choose chapter or problem)
A vacuum gage indicates that the pressure of carbon dioxide in a closed tank is \(-10 \mathrm{kPa}\). A mercury barometer gives the local atmospheric pressure as \(750 \mathrm{mmHg}\). Determine the absolute pressure of the carbon dioxide, in kPa. The density of mercury is \(13.59 \mathrm{~g} / \mathrm{cm}^3\) and \(g=9.81 \mathrm{~m} / \mathrm{s}^2\).
