A. The purge valve is an auxiliary nitrous solenoid that is activated manually by the driver prior to a nitrous assisted pass. This solenoid vents the gaseous nitrous from the supply line that connects the nitrous bottle to the nitrous solenoid. This allows a pure liquid nitrous charge to enter the engine for an instant surge of power. A purge valve is worth about a tenth of a second on a quarter mile pass. Yes, everyone needs a purge valve.
Economic growth means a higher standard of living, provided population does not grow even faster. And if it does, then economic growth is even more important to maintain the current standard of living. Economic growth allows the lessening of poverty even without an outright redistribution of wealth. If population is growing at 2.5 percent a yearâand it is in some of the poorest nationsâthen a 2.5 percent growth rate of real GDP means no change in living standards. A 3.0 percent growth rate means a gradual rise in living standards.
Much debate has surfaced on the declining importance of agriculture to economic growth, as a consequence of a secular decline in agricultureâs contribution to GDP dating back from 1978.
