1 kg Sugar if dissolved in water what will be the BOD and COD?
0.7 kg of BOD and 1.4 kg of COD
What method of body composition assessment involves passing the body through a magnetic field?
MRI, which is not practical and is very expensive. The only people getting tested via MRI are subjects of a research project. The BOD POD has magnets to lock the door but you do not pass through a magnetic field. BOD PODs are available at many colleges and universities in Exercise Science or Nutrition departments.
What is TOD BOD in water quality measurement?
There are three OD's used Total Oxygen Demand (TOD), Chemical Oxygen Demand (COD) and Biological Oxygen Demand (BOD) They all measure the amount of oxygen that would be required to consume organic material in the water, BOD is the lowest (usually) as it measures demand from microbes eating easily digested organics (sugars etc), COD measures the demand from all other organics (alcohols etc) measured by digesting the material in strong chemical oxidants, and TOD is the total of the two. Oxygen demand is important to know in waste handling as reducing the oxygen in receiving stream can harm fish and other aquatic life.
What is the structural formula for diisopropyl acetylene?
(isopropyl)x2 = (2-methylpropane)x2 --> [C(CH3)2] x2 (center) Acetylene --> C(triple bond)C (H3C)2C(triple bond)C(CH3)2
Which is a landform that has a low elevation and a mostly flat surface?
A broad and flat area that usually low in elevation is called a plain. Plains may also be seen in highlands just like in plateaus or uplands.
Factor may affect BOD test?
The factors that may affect BOD test include: 1. The temperature at which the test is performed. 2. The amount of seeding done
What is the duration in days for BOD test for water analysis at 20 degree c?
It is usually of five days but it may either be 3 days depending upon the the BOD test.
Why cod is greater than bod?
Type your answer here... It's not. Typically, COD is greater than BOD. The COD test is used primarily as an operational control because it takes only a matter of hours, compared to 5 days for the BOD test.
What advantages and disadvantages of the COD test compared to the BOD test?

How to calculate BOD value in a sample?
if unseeded, BOD = (D1-D2)/Pif seeded, BOD = ((D1-D2)-(B1-B2)f)/PD1 = DO of diluted seeded wastewaterD2 = DO of wastewater after incubationB1 = DO of diluted seed sampleB2 = DO of seed sample after incubationf = ratio of seed volume in seeded wastewater test to seed volume in BOD test on seedP = decimal fraction of wastewater sample used. (vol. of wastewater)/(vol. of dilution water plus wastewater)Maybe that helps
Role of nitrifying bacteria in BOD test?
Nitrifying bacteria play a crucial role in the BOD (Biochemical Oxygen Demand) test. They are responsible for oxidizing ammonia to nitrate in the presence of oxygen. This helps determine the amount of biodegradable organic matter in a sample, as the oxygen is consumed during this process. By measuring the decrease in dissolved oxygen, the BOD test provides an indication of the organic pollution level in water.
When was Bod - series - created?
Bod - series - was created in 1975.
When did Bod - series - end?
Bod - series - ended in 1984.
What is BOD and COD of spent wash?
COD=100 What is Bod
Point c is in the of BOD?
