It is a device that is used to measure pressure on a fluid by balancing one column of fluid against the second column of fluid. One end of the tube in the manometer pressure gauge is connected to the place where pressure is to be measured, while the other end is open to the atmosphere...
Fluid mechanics, science concerned with the response of fluids to forces exerted upon them. It is a branch of classical physics with applications of great importance in hydraulic and aeronautical engineering, chemical engineering, meteorology, and zoolog
A barometer for measuring the pressure of the atmosphere in absolute terms is simply a manometer in which p2 is made zero, or as close to zero as is feasible. The barometer invented in the 17th century by the Italian physicist and mathematician Evangelista Torricelli, and still in use today,...
Pascal’s principle, in fluid (gas or liquid) mechanics, statement that, in a fluid at rest in a closed container, a pressure change in one part is transmitted without loss to every portion of the fluid and to the walls of the container. The principle wa
Laminar flow, type of fluid (gas or liquid) flow in which the fluid travels smoothly or in regular paths, in contrast to turbulent flow, in which the fluid undergoes irregular fluctuations and mixing. In laminar flow, the velocity, pressure, and other fl
