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, for a proposed application so that large errors in estimating Hf would be reflected in correspondingly large errors in estimating 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. Đọc tiếp “BƠM ĐẤU NỐI TIẾP”

TOTAL DYNAMIC HEAD

The main components of Total Dynamic Head are:

a) Total Discharge Head, and

b) Total Suction Head.
