A mercury barometer is one of the classic uses of static pressure head. Such barometers are an enclosed column of mercury standing vertically with gradations on the tube. The lower end of the tube is bathed in a pool of mercury open to the ambient to measure the local atmospheric pressure. The reading of a mercury barometer (in mm of Hg, for example) can be converted into an absolute pressure using the above equations. In fluid mechanics, the head is a concept that correlates the energy in an incompressible liquid to the height of an equivalent static column of that liquid. The units for all the various forms of energy in Bernoulli’s equation can also be measured in distance units. Hence, these terms are sometimes introduced as … Visa mer A velocity head can be an essential part when measuring a pump’sdischarge pressure in the domain.
