A good saturation index is falls between .3 and -.3, with a range of .5 to -.5 being acceptable. A negative number indicates corrosive water, which is bad for concrete, metal and plaster surfaces. A positive number may deposit scale or cause cloudy water. Water with a result of zero (0) is neither corrosive nor scale-forming. The index takes into consideration a number of factors: calcium hardness, alkalinity, pH, water temperature, and total disolved solids (TDS). These items are assigned a number and then plugged into a formula. This saturation index was developed by Professor W.F. Langelier from the Univeristy of California.

What is the function of index in maximum and minimum thermometer?
The index in maximum and minimum thermometers serves to indicate the highest and lowest temperatures recorded since the last reset. In a maximum thermometer, a small column of mercury rises and is held in place by a constriction, marking the highest temperature reached. Conversely, in a minimum thermometer, a spirit-filled tube allows a small index to drop to indicate the lowest temperature. These indices provide a visual reference for temperature extremes over a period of time.
How many indices does the Combined DNA Index System possess?
The Combined DNA Index System (CODIS) possesses 20 indices.
What is the index that combines air temperature and relative humidity to determine an apparent temperature?
The heat index is the index that combines air temperature and relative humidity to determine an apparent temperature. It measures how hot it feels to the body by taking into account the moisture content in the air, which affects the body's ability to cool itself through sweating. High heat indexes can indicate increased risk of heat-related illnesses like heat exhaustion or heat stroke.
Why does the unit for volume have a little 3 in the air besides it?
The little 3 in the air beside m would indicate cubic meters. A little 3 in the air beside cm would indicate cubic centimeters.
What do index fossils found in rock layers in different areas of the world indicate about that the rock layers formed?
Index fossils, which are fossils of organisms that lived during a specific geologic time and are widely distributed, indicate that rock layers found in different areas of the world were formed during the same time period. Their presence suggests that these layers are contemporaneous, allowing geologists to correlate rock strata across vast distances. This helps in reconstructing the geological history and understanding the Earth's past environments. The uniformity of index fossils across different regions implies similar ecological conditions at the time of their existence.
What do the numbers on index contour lines indicate?
The numbers of contour lines indicate altitude or elevation along that line.
What is the index of 3 to the square root of 6?
The index of 3√6 is √6.
What is the index of a thermometer?
The index of a thermometer is the scale or numerical reference used to indicate temperature readings. It can be in either Celsius or Fahrenheit, depending on the type of thermometer.
The Library of Congress index uses a combination of letters and numbers to indicate?
The publication date.
What is the index of a cube root?
the index of a cube root is 3.
What is the normal brachial wrist index?
The normal brachial ankle index is typically around 1.0 to 1.4. An index below 0.9 may indicate peripheral artery disease, while an index above 1.4 may suggest arterial calcification.
What medullary index is commonly considered to indicate a human hair?
usually it's 0.33 or less...
Are preserved animal tracks index fossils?
According to the definition of "Index Fossils" the answer is no. The definition of an "Index Fossil" is - remains of an organism that lived in a particular geological age. While the track itself may indicate the age of sediment, it is not a fossil.
What does PEI of serum indicate?
PEI stands for 'PABA Excretion Index' and it is used for diagnosing pancreatic disease.
The refractive index of water is 43 and for glass it is 32 with respect to airwhat is the refractive index of glass with respect to air?
"The refractive index of water is 4 / 3" means the refractive index of water with respect to air. "The refractive index of glass is 3 /2" means the refractive index of glass with respect to air. You change the question as ," what is the refractive index of glass with respect to water? The answer is it is the ratio of refractive index of of glass with respect to air to the refractive index of water with respect to air =( 3/2) divided by( 4/3) = 1.125
What is the index of 3x3x3x3?
what is the index of 3x3x3x3
What are the factors of 216 in index notation?
The factors of 216 in index notation can be expressed as 2^3 * 3^3. This is because 216 can be broken down into its prime factors as 2 * 2 * 2 * 3 * 3 * 3, which simplifies to 2^3 * 3^3. In index notation, this represents the factors of 216 as 2 raised to the power of 3 multiplied by 3 raised to the power of 3.
