The pipe friction factor (f ) and the pressure loss coefficient for a 90-deg EL (K90 ) were measured for coal-oil slurries at Reynolds numbers less than 100. A range of mass fractions (0 to 0.4) was examined for a single particle distribution. The pipe friction factor correlated well with the established relationship for laminar flow (f = 64/ReD ) where Reynolds number is based on slurry properties. The loss coefficient for the elbow has a similar correlation.
