SLURRY FRICTION HEAD LOSSES IN PIPELINES Despite the long history of successful slurry pumping operations covering a wide range of slurries, limited published data is available to estimate Hf accurately, for every possible duty. A high degree of accuracy is normally required only if Hf represents a high proportion of the Total Dynamic Head, H,

SERIES PUMPING Many pumping duties require slurries to be transported over long distances and/or against very high static discharge heads, for example, against total heads well in excess of heads which can be developed by a single centrifugal slurry pump.

TOTAL DYNAMIC HEAD The main components of Total Dynamic Head are: a) Total Discharge Head, and b) Total Suction Head. The equation is: Total Dynamic Head = Total Discharge Head – Total Suction Head Algebraically, H = (Hd) – (Hs) (m) or, H = (Hgd + Hvd) – (Hgs + Hvs) (m) The values Hvd
