Flow work formula

WebJan 22, 2012 · The work done is pressure (assumed constant) times volume displaced. The flow work done on a unit mass that is displaced into the control volume is Pv. Pdv would be something different. This would be the work done by the fluid to expand. But the fluid does not expand, it only gets displaced. This happens to be Pv. http://www.ecourses.ou.edu/cgi-bin/ebook.cgi?topic=th&chap_sec=04.1&page=theory
