For example, methane is a much more powerful greenhouse gas than carbon dioxide. Over a 100 year period, a molecule of methane (CH4) has 21 times the warming effect as a molecule of carbon dioxide (CO2), even though it stays in the atmosphere for only about 12 years of the 100 year period.he warming impact of different types of greenhouse gases varies according to the warming power of the gas and the length of time it stays in the atmosphere. As shown in Table 1, carbon dioxide has an atmospheric life of 50 to 200 years.
hydraulic manifold definition, hydraulic manifold meaning | English dictionary. hydraulic. n a press that utilizes liquid pressure to enable a small force applied to a small piston to produce a large force on a larger piston.
Manifold vacuum should not be confused with venturi vacuum, which is an effect exploited in carburetors to establish a pressure difference roughly proportional to mass airflow and to maintain a somewhat constant air/fuel ratio. It is also used in light airplanes to provide airflow for pneumatic gyroscopic instruments.anifold vacuum, or engine vacuum in an internal combustion engine is the difference in air pressure between the engine's intake manifold and Earth's atmosphere.
