What is the relationship between the optical density (OD) and absorbance in spectrophotometry?
In spectrophotometry, optical density (OD) and absorbance are directly related. As the OD increases, the absorbance also increases. This means that a higher OD value indicates a higher absorbance of light by the sample being measured.
What is the difference between "os" and "od" in eye prescriptions?
In eye prescriptions, "OS" refers to the left eye and "OD" refers to the right eye.
How many cubic feet of nitrogen is need to fill a pipe 8 inch od by 100 ft length?
To calculate the volume of the pipe, we first need to determine the cross-sectional area using the formula A = πr^2, where r is the radius (4 inches). Then, multiply the cross-sectional area by the length of the pipe to find the volume in cubic inches. Finally, convert the volume from cubic inches to cubic feet by dividing by 1728.
Why taking culture OD at 660 NM?
see od measures the light scattering and light scattering inversely varies with the wavelength. So smaller wavelength say 430nm would be more sensitive than longer wavelength say 660nm but here we take od in LB media and yellow colour absorbs shorter wavelngth so to obviate the error due to absorbance we take od at 660nm. -Satya Pal Arya
What type of laser light source is used in bug lab od scanner?
Bug Lab OD scanners typically use red laser light sources. These lasers are chosen for their efficiency in detecting insects and other pests that may be present in the scanned materials.
What is the LCM od 21 and 35?
Least Common Multiple (LCM) for 21 35 is 105.
Why pipe NB is different with OD up to 12 inches?
Based on the NPS and schedule of a pipe, the pipe outside diameter (OD) and wall thickness can be obtained from reference tables such as those below, which are based on ASME standards B36.10M and B36.19M. For example, NPS 14 Sch 40 has an OD of 14 inches and a wall thickness of 0.437 inches. However the NPS and OD values are not always equal, which can create confusion.For NPS â…› to 12 inches, the NPS and OD values are different. For example, the OD of an NPS 12 pipe is actually 12.75 inches. To find the actual OD for each NPS value, refer to the tables below. (Note that for tubing, the size is always the actual OD.)For NPS 14 inches and up, the NPS and OD values are equal. In other words, an NPS 14 pipe is actually 14 inches OD.The reason for the discrepancy for NPS â…› to 12 inches is that these NPS values were originally set to give the same insidediameter (ID) based on wall thicknesses standard at the time. However, as the set of available wall thicknesses evolved, the ID changed and NPS became only indirectly related to ID and OD.For a given NPS, the OD stays fixed and the wall thickness increases with schedule. For a given schedule, the OD increases with NPS while the wall thickness stays constant or increases. Using equations and rules in ASME B31.3 Process Piping, it can be shown that pressure rating decreases with increasing NPS and constant schedule.[note 1]

What is is the OD of a 40 inch nominal bore blak steel pipe?
The outside diameter (OD) of a 40-inch nominal bore black steel pipe is typically 40 inches, as the nominal size refers to the approximate internal diameter of the pipe. However, the actual OD for standard pipe sizes can vary; for a 40-inch nominal bore, the standard OD is approximately 42.16 inches according to the American National Standards Institute (ANSI) specifications. This discrepancy is due to the wall thickness of the pipe, which is accounted for in the nominal size.
