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

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.
