| Gravity: | (english) An attractive force between two objects; each object accelerates at a rate equal to the attractive force divided by the object's mass. Objects near the surface of the earth tend to accelerate toward the earth's center at a rate of ; this value is often called the gravitational constant and denoted as g. |
| Gas stripping | (Environmental Engineering) Gas transfer of an undesirable gas from a water stream to the atmosphere. |
| Global warming | (Environmental Engineering) The long-term warming of the plant due to increases in greenhouse gases which trap reflected light preventing it from exiting to space. |
| Greenhouse gases | (Environmental Engineering) Gases which trap solar radiation. Of the solar energy entering the earth's atmosphere a portion is reflected back and a portion penetrates onto the earth's surface. The portion reflected back from the earth's surface is at a different wavelength that when it entered. Carbon dioxide and other gases, which pass solar radiation, absorb this reflected radiation, increasing the earth's temperature. This is much like a greenhouse, hence the name. |
| Groundwater | (Environmental Engineering) Water which is contained in geologic strata. Also properly written as two words, ground water. |
| Go, no-go decision - | (Software Engineering) a point at which manager or the customer decides whether the project should proceed |
| GQM (Goal, Question, Metric) paradigm - | (Software Engineering) a technique for defining meaningful metrics for any part of the software process |
| Grammatical parse - | (Software Engineering) a technique that is used during analysis and intended to help isolate basic data objects and functions |
| GFRC - Glass Fiber Reinforced Concrete | (Concrete Engineering) Concrete panels, usually architectural designs, reinforced with a high zirconia (16% minimum), alkali-resistant glass fiber. Optimum glass fiber content of 5% by weight. Lower fiber content results in lower early ultimate strengths, higher fiber content can produce composite compaction and consolidation difficulties. |
