where ΔT is the difference between the hydrate-formation temperatures in the presence of pure water and in a methanol solution (°C), Mj is the molecular weight of the inhibitor j, and yj is the weight percent concentration of inhibitor j, and kj is a constant value for different inhibito...
Specific gravity (SG) is the density of the gas relative to air, which has a specific gravity of 1. The higher the specific gravity, the heavier the gas and so the slower the flow of gas through a burner jet at a constant pressure. A heavy gas with a higher specific gravity must the...
The flow characteristic is normally given at steady state, with the inlet at a constant, carefully controlled pressure. The flow characteristic depends only on the valve and can be linear or nonlinear. To capture the flow characteristics, use theOpening characteristicparameter: ...
Notes 1. The static lifetime of a raw material is the ratio of the reserves or the total resources (sum of reserves and resources) of a raw material to its annual output and corresponds to the number of years that a non-renewable raw material is globally available assuming constant consumpt...
Constant weight on bit can be applied, thus increasing ROP. ; Mechanical transmission;Compound transmission; HOISTING SYSTEM Function: The hoisting system is used to lower and raise drillstring and casing into and out of the well Components: Derrick or mast, drawworks, crown block, travelling ...
Fixed costs remain constant regardless of production or activity levels, whereas variable costs differ depending on the level of activity or output [117]. Another distinction is between relevant and irrelevant costs [118]. Relevant costs are defined as costs associated with a specific decision. The...
As a fixed sample of gas is compressed to a smaller volume at constant temperature, its pressure increases. This happens because forcing the same number of molecules into a smaller volume makes more collisions with their container, thus exerting more pressure. ...
Define ideal gas. ideal gas synonyms, ideal gas pronunciation, ideal gas translation, English dictionary definition of ideal gas. n. A gas having particles that have perfectly elastic collisions and negligible volume and intermolecular forces, thus exact
Solution:The trick here is to note that the total number of molesnTand the temperature remain unchanged, so we can make use of Boyle's lawPV= constant. We will work out the details for CO2only, denoted by subscriptsa. For CO2,PaVa= (2.13 atm)(1.50 L) = 3.19 L-atm. ...
The Individual Gas Constant depends on the particular gas and is related to the molecular weight of the gas. The value is independent of temperature. The induvidual gas constant, R, for a gas can be calculated from the universal gas constant, Ru ( given in several units below), and the ...
