Executive Preface
An introduction to the content and overall objectives of the IFPRI research programme of work was presented in Stage I report where the available results were evaluated with the aim of writing a Design Guide. Recapitulating briefly, the IFPRI work was instigated in order to:
1. Develop new, physically based correlations which describe rigorously the flow behaviour of non-colloidal settling slurries and which may be used to predict accurately the head loss in straight pipes and essential, standard pipe fittings.
2. Validate the use of existing, well accepted correlations describing the flow behaviour of colloidal slurries for industrial scale-up design calculations, obtain representative head loss data forstandard pipe fittings and finally, establish the optimum rheological slurry properties required to minimise the power consumption with hydraulic transportation.
This report entitled “IFPRI Design Guide, (Stage II)” is a first step towards producing a concise document based on the findings of the IFPRI programme of work. The penultimate objective is to resolve the-uncertainties associated with known design procedures and hence to provide a comprehensive and reliable source of reference for the design of hydraulic conveying systems needed in industrial applications.
