Web5 mrt. 2024 · Ho, also called the specific energy, is simply the head (i.e., flow energy per unit weight) relative to the channel bottom. Using Ho, Equation 5.4.4 becomes. Ho2 + … WebKinetic pumps can be divided into two classes, centrifugal and regenerative. In kinetic pumps a velocity is imparted to the fluid. Most of this velocity head is then converted to pressure head. Even though the first centrifugal pump was introduced about 1680, kinetic pumps were little used until the 20th century. Centrifugal pumps include radial, axial, …
