Webb14 apr. 2024 · The long-term creep behavior of salt rocks is uncertain. Generally, the creep behavior of salt rocks is measured at the laboratory scale. In laboratory deformation experiments, the differential stress is 1 MPa or higher, and the typical strain rate ranges from 10 −9 s −1 to 10 −6 s −1.We developed a long-term creep model for salt rocks, … WebbPump Head – Performance Curve. In fluid dynamics, the term pump head is used to measure the kinetic energy which a pump creates. Head is a measurement of the height of the incompressible fluid column the pump could create from the kinetic energy that the pump gives to the liquid. The head and flow rate determine the performance of a pump, …

WebbThe pump characteristic curves can be defined as ‘the graphical representation of a particular pump’s behavior and performance under different operating conditions’. The operating properties of a pump are established by the geometry and dimensions of the pump’s impeller and casing. WebbThe pump curve is defined by entering points for discharge rates at various heads. Since the general pump equation, shown below, is used to simulate the pump during the …
