Preliminary investigation into the rheology of dairy shed waste
1974
Dakers, A. J.
With the introduction of stricter control on the final disposal of all forms of farm waste, its transportation is becoming an everyday component of farm management. In the past and at present the design of such transportation systems has been and is being based on criteria for transportation of fresh water with little appreciation of the differences that may or may not exist. Certain research workers have found this difference to be quite significant (13, 15, 31). Estep (36) has suggested that manure pump installations should be designed for a friction loss 10% higher than for water. Grimm et ale (12) found that with total solids (T.S) less than 35,000ppm pressure loss was less than for water. Thus it might be concluded that a considerable amount of work is required before accurate flow characteristics of manure slurries can be understood.
