22McLeod gauge — A glass McLeod gauge, drained of mercury A McLeod gauge is a scientific instrument used to measure very low pressures, down to 10 6 Torr. It was invented in 1874 by Herbert McLeod (1841–1923).[1] McLeod gauges were once commonly found attached to …
23Atmospheric pressure — Air pressure redirects here. For the pressure of air in other systems, see pressure. Atmospheric pressure is the force per unit area exerted against a surface by the weight of air above that surface in the Earth s atmosphere. In most… …

28Oil pressure (internal combustion engine) — Oil pressure is an important factor in the longevity of most internal combustion engines. With a forced lubrication system (invented by Frederick Lanchester), oil is picked up by an oil pump and forced through oil galleries (drillings) into the… …
29Root pressure — Root pressure: osmotic pressure within the cells of a root system that causes sap to rise through a plant stem to the leaves.Root pressure occurs in the xylem of some vascular plants when the soil moisture level is high either at night or when… …
30High pressure steam locomotive — A high pressure steam locomotive is a steam locomotive with a boiler that operates at pressures well above what would be considered normal. In the later years of steam, boiler pressures were typically 200 to 250 PSI (1.4 to 1.7 MPa). High… …
