The logic gate that will have HIGH or "1" at its output when any one of its inputs is HIGH is a (n): . In these processes, the S.G. of separation will vary between certain limits about a mean S.G. due to fluctuations in operation conditions. "Specific gravity" is the density of a material relative to water. The specific gravity of coal is the ratio of the density of coal to that of a reference substance (Usually water). A sample for a urine specific gravity test contains at least 1 to 2 ounces of urine. 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, must weight ( syrups, juices, honeys, brewers wort, must, etc.) Relative density or specific gravity of the coal depends on the rank of the coal and degree of mineral impurity. Therefore, the specific gravity of a typical concrete mix is 145/62.4 or 2.32. Density is the mass per unit volume of a substance.
