Waste Management Glossary

and cups, and steel cans. Compactor - A type of equipment that uses pressure to compress recyclable materials into a dense mass. Compostable - Capable of undergoing biological decomposition in a compost site, such that the material is not visually...

Annular Film

and can be influenced by gravity, surface tension, and flow rate. Applications - Annular films are important in heat and mass transfer processes, as they can enhance or hinder the efficiency of such operations.

Annular Flow Flow Rate

Diameter \(in\) - \( AV \) = Annular Velocity \(ft \;/\; min\) - Flow rate in an annular flow regime is the volumetric or mass rate at which the gas and liquid phases are transported through the pipe. The flow rate is generally divided into two...

Diffusion Depth in a Geothermal Well

Pressure Drop Across a Nozzle/Orfice

flows from a wider area into the narrower opening of a nozzle or orifice, its velocity must increase to maintain a constant mass flow rate. According to Bernoulli's principle, this increase in kinetic energy is accompanied by a decrease in pressure...

Cuttings Produced per Foot of Hole Drilled

- \( \phi \) (Greek symbol phi) = Porosity \(dimensionless\) - Cuttings produced per foot of hole drilled is the volume or mass of rock fragments removed for every foot of borehole created. This value is essential for various calculations, including...

Dry Steam Enthalpy

Minimum Miscibility Pressure

dynamic process where miscibility develops through repeated contacts between the injected gas and reservoir oil. It involves mass transfer (vaporization or condensation) over multiple interactions, gradually forming a single phase. This can be divided...
