Because a competitive firm's marginal revenue is equal to the market price, the competitive firm's demand curve, which is just a horizontal line at the market price, is also the firm's marginal revenue curve.ecause a competitive firm's marginal revenue is equal to the market price, the competitive firm's demand curve, which is just a horizontal line at the market price, is also the firm's marginal revenue curve.
MMBTU â One million British Thermal Units or BTUs. Natural gas is generally bought and sold in MMBTUs and future prices are generally quoted in this unit of measure. Therm â 1 Therm = 100,000 BTUs. SCF â Standard Cubic Foot is one cubic foot of gas at standard temperature and pressure (60 degrees F and sea level).
A sulphur-based odourant is normally added to CNG to facilitate leak detection. Natural gas is lighter than air and thus will normally dissipate in the case of a leak, giving it a significant safety advantage over gasoline or LPG. Liquefied Natural Gas or LNG is natural gas stored as a super-cooled (cryogenic) liquid. The temperature required to condense natural gas depends on its precise composition, but it is typically between -120 and -170Â°C (-184 and â274Â°F). The advantage of LNG is that it offers an energy density comparable to petrol and diesel fuels, extending range and reducing refuelling frequency.
