Material Flow in Pipe

[ehderube]

Hello,

I'm trying to calculate the bulk material flow (kg/sec.) in a pipe (15.75" ID, gravity feed). The material is coal. Does anybody know of any resources that discuss this topic or derives the equations? Particle size would be >500 mircon, bulk density of ~800kg/m^3.

Thanks in advance,
Ed
