Standard cubic centimeters per minute (SCCM) is a unit used to quantify the flow rate of a fluid. 1 SCCM is identical to 1 cm³ STP /min. Another expression of it would be Nml/min.
the volume of a cube of side length one decimetre (0.1 m) equal to a litre 1 dm 3 = 0.001 m 3 = 1 L (also known as DCM (=Deci Cubic Meter) in Rubber compound processing) Cubic centimetre [5] the volume of a cube of side length one centimetre (0.01 m) equal to a millilitre 1 cm 3 = 0.000 001 m 3 = 10 −6 m 3 = 1 mL Cubic millimetre
The kilogram per cubic metre (symbol: kg·m −3, or kg/m 3) is the unit of density in the International System of Units (SI). It is defined by dividing the SI unit of mass, the kilogram, by the SI unit of volume, the cubic metre. [1]
The clean air delivery rate (CADR) is a figure of merit that is the cubic feet per minute (CFM) of air that has had all the particles of a given size distribution removed. For air filters that have air flowing through them, it is the fraction of particles (of a particular size distribution) that have been removed from the air, multiplied by the ...
[3] [4] Thionyl chloride first reacts with the alcohol to form an alkyl chloro sulfite , actually forming an intimate ion pair . The second step is the loss of a sulfur dioxide molecule and its replacement by the chloride, which was attached to the sulphite group.
For ozone (O 3), the guidelines suggest values no higher than 100 μg/m 3 for an 8-hour mean and 60 μg/m 3 peak season mean. [2] For nitrogen dioxide (NO 2), the guidelines set 10 μg/m 3 for the annual mean or 25 μg/m 3 for a 24-hours mean. [2] For sulfur dioxide (SO 2), the guidelines stipulate concentrations not exceeding 40 μg/m 3 24 ...
Clean air delivery rate (CADR) is the amount of clean air an air cleaner provides to a room or space. When determining CADR, the amount of airflow in a space is taken into account. For example, an air cleaner with a flow rate of 30 cubic metres (1,000 cu ft) per minute and an efficiency of 50% has a CADR of 15 cubic metres (500 cu ft) per minute.
In the United States most utilities bill only to the nearest 100 or 1,000 gallons (10 to 100 ft 3, 1 to 10 m 3), and often only read the leftmost 4 or 5 numbers on the display wheels. Using the above example, they would read and bill 1,234, rounding to 1,234,000 gallons based on a 1,000-gallon billing resolution.
