One of the National Academy of Engineering Grand Challenges for Engineering is Develop Carbon Sequestration Methods. The NAE defines carbon sequestration as "capturing the carbon dioxide produced by burning fossil fuels and storing it safely away from the atmosphere." The most promising storage location is underground, possibly in sedimentary brine formations. You are assigned to develop instrumentation to measure the properties of a brine formation, located 800 meters [m] deep.
Assume the instruments will feel an equivalent amount of pressure to the amount of hydrostatic pressure felt at the bottom of an 800-meter [m] high column of brine, with a specific gravity of 1.35.
1. To what hydrostatic pressure, in units of atmospheres [atm], must the instrumentation be built to withstand?
