Anthropology has been put to practical use throughout its history, but the field of applied anthropology dates to 1941 with the formation of the Society for Applied Anthropology.t is, quite simply, anthropology put to good use. This fifth field of anthropology has increased dramatically in the past three decades. Today, most anthropology graduates pursue applied rather than academic careers.
Measurement. The manometer is placed against a measured scale to allow any difference in the height of the two columns. This height differential can be used directly to make relative comparisons between different test pressures.xample. Assume that the fluid in the manometer is mercury and the height of the fluid in the reference column is .02 meters higher than the height of the fluid in the test column.
A hydrometer or areometer is an instrument that measures the specific gravity (relative density) of liquidsâthe ratio of the density of the liquid to the density of water. A hydrometer is usually made of glass, and consists of a cylindrical stem and a bulb weighted with mercury or lead shot to make it float upright. The liquid to test is poured into a tall container, often a graduated cylinder, and the hydrometer is gently lowered into the liquid until it floats freely. The point at which the surface of the liquid touches the stem of the hydrometer correlates to specific gravity.
