PRESSURE AND SWIRL OF LIQUID ON THE OUTLET OF CENTRIFUGAL PUMP IMPELLER

摘要

Divergences between values of potential head H p of a centrifugal pump, computed from different literature formulae, are discussed. The new, more accurate, formulae for head H p and swirl coefficient c' u2 calculation are derived. One dimensional (Euler) theory of hydraulic turbomachines is applied.
