Bulk soilds transport through 5" pipe

[Skoogen]

Has anyone have any suggestions where to look for equations and factors related to moving solids through a pipe using compressed air.

I am designing a system to move barium sulphate, bentonite and cement powders on an oil rig. I am somewhere close to be able to design a system but am lacking K values for various pipes for different pressures and pipe sizes.

I would appreciate it if someone can point me in the right direction with this.

Thanks

Alex Chatwin
