This paper deals with the pressure loss of Bingham plastic fluid flow through packed beds. With help of tube-bundle model a friction factor and Reynolds number relationship for laminar flow is derived as Eq.(16).
The present experimental investigation covers the range of Reynolds number defined by Eq.(21) from 4×10-3 to 8×102 and of Bingham number up to 3×103.
It is confirmed by the experiment that the flow behavior in the range of Reynolds number defined by Eq.(15) up to 10 shows the laminar state.
An empirical equation of friction factor defined by Eq.(14) for laminar flow obtained as Eq.(25). It is observed that 362 out of the 489 data in laminar flow were within ±10% of the values calculated from Eq.(25).
