The rate of doing work or the rate of expending energy. Used to measure the salt content of water. If 1 pound of sea salt were dissolved in l,000,000 pounds of water, the sea salt concentration would be 1.00 ppm. A pre-cision type of bearing consisting of an upper and lower shell. A portion of the combustion chamber connected to the cylin-der through a narrow throat.
Fuel is injected into and is partly burned in the precombustion chamber.
Heat released by this partial burning causes the contents of the precombustion chamber to be ejected into the cylinder with considerable turbulence. The amount of force distributed over each unit of area. The dif-ference in pressure between any two points of a system or a component. A valve designed to open when pressure in the system exceeds a certain limit. An electrical switch operated by the increase and decrease of pressure.
