### mass balanceSchlumberger Oilfield Glossary

Assumptions are (1) masses and volumes of components are additive and (2) material is neither generated nor lost from the system. As a simple example, below are the two material-balance equations for a three-component mixture of oil (o), water (w) and solids (s), where V = volume percent, D = specific density and MW = mixture weight.

### Boundary layerWikipedia

In physics and fluid mechanics, a boundary layer is the layer of fluid in the immediate vicinity of a bounding surface where the effects of viscosity are significant.. In the Earth's atmosphere, the atmospheric boundary layer is the air layer near the ground affected by diurnal heat, moisture or momentum transfer to or from the surface. On an aircraft wing the boundary layer is the part of the

### Hydrocyclone Phenomenological-Based Model and Feasible

Common mass conservation and mechanical energy balance (Bernoulli’s equation) was applied in order to cover the behavior of pulp inside the hydrocyclone. Through that approach, physical characteristics of overflow and underflow streams were predicted reaching a good agreement between experiments and model predictions.
