Open Method
An open water cooling system makes use of evaporative cooling, lowering the temperature of the remaining (unevaporated) water. This method was common in early internal combustion engines, until scale buildup was observed from dissolved salts and minerals in the water. Modern open cooling systems continuously waste a fraction of recirculating water as blowdown to remove dissolved solids at concentrations low enough to prevent scale formation. Some open systems use inexpensive tap water, but this requires higher blowdown rates than deionized or distilled water. Purified water systems still require blowdown to remove accumulation of byproducts of chemical treatment to prevent corrosion and biofouling.

Famous quotes containing the words open and/or method:
“The child ... stands upon a place apart, a little spectator of the world, before whom men and women come and go, events fall out, years open their slow story and are noted or let go as his mood chances to serve them. The play touches him not. He but looks on, thinks his own thought, and turns away, not even expecting his cue to enter the plot and speak. He waits,—he knows not for what.”
—Woodrow Wilson (1856–1924)
“I do not know a method of drawing up an indictment against a whole people.”
—Edmund Burke (1729–1797)
