Effluent based standards
แปลว่า(Environmental Engineering) Standards which set concentration or mass per time limits on the effluent being discharged to a receiving water.
effluent
แปลว่าน้ำทิ้ง [ป่าไม้]: น้ำออก [สิ่งแวดล้อมน้ำ]
Secondary standards
แปลว่า(Environmental Engineering) Recommended drinking water quality standards which relate to aesthetics and/or health. These standards are recommended, not required. See primary standards.
Primary standards
แปลว่า(Environmental Engineering) Required drinking water quality standards related directly to human health. These standards are required and enforceable by the U.S. EPA. See secondary standards.
Receiving water quality standards
แปลว่า(Environmental Engineering) Standards which require a discharger to maintain a certain quality level in the receiving water.
Influent
แปลว่า(Environmental Engineering) The fluid entering a system, process, tank, etc. An effluent from one process can be an influent to another process. See effluent.
Statistical quality assurance
แปลว่า(Software Engineering) techniques for process improvement that are based on measurements of the product and the process
Vapor Pressure
แปลว่า(Concrete Engineering) The pressure exerted by a vapor that is calculated based upon relative humidity and temperature. The higher the humidity and higher temperature, in degrees Fahrenheit, the greater the vapor pressure exerted.
Unit Water Content
แปลว่า(Concrete Engineering) The quantity of water per unit volume of freshly mixed concrete, often expressed as gallons or pounds per cubic yard. This is the quantity of water on which the water cement ratio is based, and does not include water absorbed by the aggregate
Water Vapor Pressure
แปลว่า(Concrete Engineering) The pressure exerted by water vapor. Air that contains higher amounts of water vapor exerts a higher vapor pressure than air which has a lower amount of has a higher water vapor pressure In concrete water vapor pressure is calculated by the difference between the vapor pressure of the concrete and the ambient relative humidity and temperature and in contact with the soil. that is calculated by; based upon relative humidity and temperature. The greater the difference between the water vapor and ambient humidity and temperature, in degrees Fahrenheit. the greater the water vapor pressure exerted.
