About Syrah Slurry

Most engineers active in field of fluid mechanics and mining engineering require calculating the pressure drop inside both homogeneous and slurry pipelines. Current available tools for such purposes are not capable of integrating these calculations inside commercially available spreadsheet softwares (e.g. Microsoft Excel and Google Document) . Our goal is to increase the capabilities of these software by addition of engineering function package. This package is capable of addition of following functions to your spreadsheets:

• Slurrydpdx (Pressure drop inside slurry pipelines)
• Vdeposition (Deposition velocity inside slurry pipeline)
• Standarddpdx (Pressure drop inside homogeneous pipelines)
• PipeReynolds (Pipe Reynolds number)
• Clayviscosity (Viscosity of clay slurries)
• Churchill (Churchill friction factor)

As these functions are based in cloud, the user is capable of using them from any device connected to internet. For example, you can easily calculate the pressure drop inside a 20% (by volume) sand + water pipeline, using your cell phone.

Model

The model used in this package to calculate the pressure gradient inside the slurry pipelines is based on Wilson's two-layer model ^[1]. In general the pipeline is broken into two hypothetical layers of constant velocity and concentration.

To check the reliability of the package (i.e. slurrydpdx function), model predictions has been compared with experimental data ^[2]:
