For the other version, it it is the reverse. But both versions are consistent in that for each version work done by the fluid decreases the energy of the fluid and work done on the fluid increases the energy of the fluid. Bottom line: IMO. rayhan delivery qatar

"WebThe work term, therefore can be broken into a "shaft" component and a "flow" component: DEFINITION: Flow work is the energy necessary to cause flow in an open system. DEFINITION: Shaft work is any mechanical energy other than that necessary for flow. Typically this requires a stirrer or turbine (hence the name "shaft" work). Mathematically, … " - Flow work formula
