The northeast gas association nga operating committees and special project. A comparison between real and ideal gas in theoretical cavitation. An ideal gas is one that conforms exactly to the tenets of the kinetic molecular theory, where the volume occupied by the gas particles is negligible relative to the total volume of the container, and there are no appreciable intermolecular attractions or repulsions real gases can deviate from ideal behaviour, especially at high pressures and low temperatures. The uk gas market became a public discussion point in the period from 1967 to 1977 during the switchover from town gas, made from coal, to natural gas, following the discovery of natural gas in the uk sector. At low densities the pressures become even closer and obey the ideal gas law. Natural gas is moved by pipelines from the producing fields to consumers.
We will also learn and understand the definition of absolute temperature and its utility in the study of thermal properties of matter. The treatment if the natural gas from the field is wet, it undergoes a preliminary conditioning to separate methane from the other gaseous hydrocarbons such as propane, butane and ethane.
