When oil is produced to surface temperature and pressure it is usual for some natural gas to come out of solution. The gas/oil ratio (GOR) is the ratio of the volume of gas ("scf") that comes out of solution to the volume of oil — at standard conditions.
Atmospheric pressure is the total weight of the air above unit area at the point where the pressure is measured. Thus air pressure varies with location and weather . If the entire mass of the atmosphere had a uniform density equal to sea-level density (about 1.2 kg/m 3 ) from sea level upwards, it would terminate abruptly at an altitude of 8.50 ...
Summary of basic size, fundamental deviation and IT grades compared to minimum and maximum sizes of the shaft and hole. Dimensional tolerance is related to, but different from fit in mechanical engineering, which is a designed-in clearance or interference between two parts.
In 1901, at the 3rd CGPM conference, the litre was redefined as the space occupied by 1 kg of pure water at the temperature of its maximum density (3.98 °C) under a pressure of 1 atm. This made the litre equal to about 1.000 028 dm 3 (earlier reference works usually put it at 1.000 027 dm 3 ).
The CuOFP capsule used as overpack for spent nuclear fuel disposal in the KBS-3 concept (Swedish version). Oxygen-free copper (OFC) or oxygen-free high thermal conductivity (OFHC) copper is a group of wrought high-conductivity copper alloys that have been electrolytically refined to reduce the level of oxygen to 0.001% or below.
The main driving force of cross-flow filtration process is transmembrane pressure. Transmembrane pressure is a measure of pressure difference between two sides of the membrane. During the process, the transmembrane pressure might decrease due to an increase of permeate viscosity, therefore filtration efficiency decreases and can be time ...
A gas flare produced by a landfill in Lake County, Ohio. Landfill gas is a mix of different gases created by the action of microorganisms within a landfill as they decompose organic waste, including for example, food waste and paper waste.
Beryllium carbide is prepared by heating the elements beryllium and carbon at elevated temperatures (above 950°C). It also may be prepared by reduction of beryllium oxide with carbon at a temperature above 1,500°C:
