The Paterson & Cooke Slurry Calculator is a simple calculator of slurry properties. Use it to determine the concentration of the slurry if you know the density or vice versa. It is also a useful tool to determine mass transfer rates.
The Paterson & Cooke Slurry Slump Calculator is a simple calculator to estimate slurry yield stress from the measured slump. It is based on the following paper: Pashias N, Boger DV, Summers J, Glenister DJ "A 50 Cent Rheometer for Yield Stress Measurement", Journal of Rheology, Vol.40, No.6, 1179-1189, 1996.
Paterson & Cooke has developed a Smartphone App which offers the following useful tools: Mass Balance Calculator, Water Pipeline Friction Losses, Slump Yield Stress Estimate, Standard Mesh Sieve Sizes and Useful Unit converter.
