Enthalpy fenceline
WebWhat is Enthalpy. The enthalpy is defined to be the sum of the internal energy E plus the product of the pressure p and volume V. In many thermodynamic analyses, the sum of the internal energy U and the product of pressure p and volume V appears. Therefore it is convenient to give the combination a name, enthalpy, and a distinct symbol, H. WebAs nouns the difference between fence and fenceline is that fence is a thin, human-constructed barrier which separates two pieces of land or a house perimeter while fenceline is the area immediately around a fence. As a verb fence is to enclose, contain or separate by building fence.
