Inclined Pipe Correction

Adjustment method applied to settling slurry flow calculations in FluidFlow to account for pipe inclination effect on deposition limit velocity.

One of these two correction methods configurable in the Slurry calculation options can be applied:

• Wilson – Tse 1984 Chart
• Extended Wilson – Tse 1984 Chart

The procedures for correcting deposition velocity for pipe inclination are generally the same, except that the Extended Wilson-Tse 1984 chart accounts for particle size to diameter ratio (d_{50}/D) when calculating changes in the Durand deposition parameter, particularly for ratios between 0.003 and 0.04.

This correction is applied for pipe inclinations between -20° and 80°. Beyond this range, the pipe is considered vertical.
