WebPurpose To investigate the effect of different methods of head elevation on intraocular pressure (IOP) in patients with open-angle glaucoma (OAG). Methods Seventy-one patients of OAG were included in this prospective observational study. We measured IOP in the sitting position and in the supine positions with head flat and 30-degree up using ... In fluid dynamics, head is a concept that relates the energy in an incompressible fluid to the height of an equivalent static column of that fluid. From Bernoulli's principle, the total energy at a given point in a fluid is the energy associated with the movement of the fluid, plus energy from static pressure in the fluid, plus … See more Hydraulic head or piezometric head is a specific measurement of liquid pressure above a vertical datum. It is usually measured as a liquid surface elevation, expressed in units of length, at the entrance (or … See more After free falling through a height $${\displaystyle h}$$ in a vacuum from an initial velocity of 0, a mass will have reached a See more The distribution of hydraulic head through an aquifer determines where groundwater will flow.
