A20,000 gallon tank is discovered buried below the land surface and has been leaking slowly for many years, As the lead scientist you submerse a pressure gauge 2 feet below the liquid surface in the tank. The pressure gauge reads 114.8 Ibvft What is the chemical liquid in the tank given that you have a chart of Specific Gravity for different chemicals? Benzoic sulfide hexanone Ethylbenzene Dichloromethane Trichloroethene Sulfuric acid 0.69 0.92 1.65 1.46 1.10 Land Surface 2 ft Type here to search 229 PM 1019/17

Explanation / Answer

ANSWER:

Specific gravity is the ratio of the density of a substance to the density of a reference substance; equivalently, it is the ratio of the massof a substance to the mass of a reference substance for the same given volume. Apparent specific gravity is the ratio of the weight of a volume of the substance to the weight of an equal volume of the reference substance. The reference substance is nearly always waterat its densest (4°C) for liquids; for gases it is air at room temperature (25°C). Nonetheless, the temperature and pressure must be specified for both the sample and the reference. Pressure is nearly always 1 atm (101.325 kPa). Temperatures for both sample and reference vary from industry to industry. In British beer brewing, the practice for specific gravity as specified above is to multiply it by 1000.[1] Specific gravity is commonly used in industry as a simple means of obtaining information about the concentration of solutions of various materials such as brines, hydrocarbons, sugar solutions (syrups, juices, honeys, brewers wort, must etc.) and acids.
