Ideal Gases under Constant Volume, Constant Pressure

Constant Temperature Process If T = const., then dT = 0, and, from 1, d(pV) = 0, i.e., pressure and volume are inversely proportional. Further, from 2, dq = p dV; i.e., there is no change in internal energy (from 3, du = 0), and all the thermal input to the gas goes into the work of expansion.

Guided wave radar in saturated steam applications

A boiler is a closed vessel in which water is heated. The heated or vaporised fluid exits the boiler for use in various processes, including boiler-based power generation. Most boilers produce steam to be used at saturation temperature; that is, saturated steam. The source of heat for a boiler is typically the combustion of coal. However,

Condensing Temperature Clues - ACHR News

Mar 30, 2004 · This change from vapor to liquid happens at one temperature; the temperature remains constant while phase changing, even though heat is being removed. (Note: An exception to this occurs in the 400 series refrigerant blend, which has a temperature change [glide] when phase changing.) This one temperature is the saturation temperature.
