t apply at all in other cases. The impelling power in centrifugal pumping consists of two separate forces, centrifugal force, and what is called tangential energy, or " mechanical push," due to the action of the vanes and force of discharge from the impeller, but these forces vary relatively with… … Fig. 1. Referring to Fig. 1 it will be seen that the casing is in effect a portion of the discharge pipe, and may be thus considered, so a con- stant velocity of flow therein can be assumed for all heads. This being constant, and the tangential energy or velocity of discharge
