The runoff coefficient (C) represents the fraction of rainfall that becomes surface runoff and varies by land use — for example, C ≈ 0.90 for impervious pavement versus C ≈ 0.25 for lawns with sandy soil.
2. Which greenhouse gas has the highest 100-year Global Warming Potential (GWP) relative to CO₂?
Sulfur hexafluoride has a 100-year GWP of approximately 23,500, the highest of any gas regulated under the Kyoto Protocol.
3. What is the primary purpose of a water system's storage tank (elevated or ground-level)?
Water storage tanks equalize daily demand variations, maintain system pressure, and provide reserve capacity for fire fighting and emergencies.
4. Which system is commonly used to treat municipal wastewater?
Municipal wastewater, which includes sewage from homes and businesses, contains various contaminants that must be removed before it can be safely discharged. Wastewater treatment plants are specialized facilities designed to purify this water through a series of physical, chemical, and biological processes. This comprehensive treatment ensures the water meets strict regulatory standards, preventing pollution and protecting public health and aquatic ecosystems.
