Determining Discharge Rates of Particulate Solids | AIChE

Table 1. The underlying physics of liquids and solids are very different. When liquids are stored in tanks and discharged: provided the tank is vented, the discharge rate depends on the liquid level above the discharge orifice. Unlike pressure in liquids, which is a scalar quantity, stress in bulk solids is a tensor.
