The rheological behaviour of the slurry follows the power-law model, with m = 5.55 Pa·s n and n = 0.35. The volumetric flowrates of air and liquid are 7.48 m 3 /h and 1.75 m 3 /h respectively.
WebbIf you are unsure of pipe size selection, as a general guide you may wish to select pipe sizes by limiting the pressure loss to around 300 Pa per meter. Alternatively you could limit the velocity to 1 m/s for small bore pipes, between 0.75 and 1.15 m/s for 15mm to 50mm pipes and 1.25 m/s to 3 m/s for pipes larger than 50mm. WebbThe recommended design slurry velocities range from 4 to 7 ft/s. Pipe abrasion can be a problem for some types of solids when the velocity approaches 10 ft/s. For velocities below 4 ft/s there can be a tendency for solids to settle and create blockage and plugging of the line. Sign in to download full-size image.
