  Wood Moisture Calculations
The weight of moisture contained in a piece of wood expressed as a percentage of its oven dry weight is almost universally referred to as its moisture content.
Furthermore, expressed as a percentage of oven dry weight, moisture content is readily envisaged since it represents the amount of moisture contained in the wood as parts by weight of water to 100 parts of wood substance.
The oven dry weight of a sugar maple specimen is 100 grams.

 YOR - Grams Dry Weight Field Information
Dry Weight in Grams (per square foot of canopy), and the method used to determine that weight.
Dry weight is considered to be 25% of the fresh weight.
Although dry weight is easier to relate to for most people, fresh weight is a more accurate measure of yield because it doesn't vary with the degree of dryness or personal preferences of the grower.

 dry - definition by dict.die.net
Dry rot, a decay of timber, reducing its fibers to the condition of a dry powdery dust, often accompanied by the presence of a peculiar fungus (Merulius lacrymans), which is sometimes considered the cause of the decay; but it is more probable that the real cause is the decomposition of the wood itself.
Dry stove, a hothouse adapted to preserving the plants of arid climates.
Dry wine, that in which the saccharine matter and fermentation were so exactly balanced, that they have wholly neutralized each other, and no sweetness is perceptible; -- opposed to sweet wine, in which the saccharine matter is in excess.

 Arizona Rangelands: Inventory and Monitoring: Dry-Weight Rank Method
To follow this technique, in each quadrat the observer identifies the first, second, and third most abundant species (on a dry weight basis), to which the ranks of 1, 2, and 3, are respectively assigned.
At the end of sampling, ranks are tallied for each species, and weighted by a set of multipliers, usually 0.7 for Rank 1, 0.2 for Rank 2 and 0.1 for Rank 3.
The weighted values of the three ranks are then added together for each species, and the result represents species composition.

 wet dry drying study
Drying "Wet" means that the relative humidity (RH) of the coating was at ambient and relatively high (typically 60-70% RH) when exposed.
Drying "Dry" means that the ambient RH was relatively low (preferably less than 40% RH) and the print dried by blowing air with medium heat over the coating to dry as much as possible.
The weight of the coating chemistry minus water except for the 6H2O attached to the FO is calculated to be about 0.0203 grams assuming none lost.

 Post-Maturity Kernel Dry Weight Loss (Purdue University)
The objective was to determine whether dry weight of mature corn kernels changes during normal drydown periods in the field.
Physiological maturity of the corn kernels, defined as the point of maximum kernel dry weight, occurred at an average grain moisture content of 28.4 percent, and ranged from 25 to 35 percent during the course of the study.
During the three years where kernel dry weight losses were observed, the average rate of kernel dry weight loss, per thousand kernels, was about 3.4 grams (or about one percent) per point decrease in grain moisture content (Table 1).

A light weight cementitious composition comprising a dry mixture of a hydraulic cement component and an aggregate component and which, upon mixing with water, produces a paste which is easily workable and sets to produce a light weight concrete mass.
While the dry cementitious mixture of the present invention normally will be used alone, it can be combined with the normal (heavier) weight concrete mixtures to economically meet special requirements such as in special finishing and very high compressive, tensile, and shear strength requirements.
In accordance with the invention, the cementitious composition comprises a dry flowable mixture of a multi-constituent hydraulic cement component and a light weight aggregate component.

Compute the moisture content of the sample by dividing the weight of the removed water by the oven dry weight of the sample.
Weight changes will not be very dramatic until the sample heats up enough for evaporation to begin.
When weight changes of 0.1 grams to 0.2 grams occur, smell the sample for "smoke." When weight changes of 0.3 grams begin, consider shortening the drying interval to 10 seconds.

Dry weight is the weight of the product with all the water removed.
Reed Mariculture measures dry weight in our microalgae products by placing 100 grams of concentrate into an 80' C drying over and cooking until nothing is left but powder.
The microalgae community has long known that cell counts are a very poor method of measuring algae when it is being used for feeding other organisms because the size and weight of the algae cells vary based on temperature, amount of light, and photo period.

 YOR - About Weights and Yields
Because fresh weight is a more accurate way of reporting yields, but dry weight had established itself as the default nomenclature when discussing cannabis weight, the YOR needed to find a way to avoid listing both types of weights so that users of the database wouldn't have to make mental adjustments for each yield report.
The answer was to allow actual dry weights to be listed when the fresh weight wasn't known, but when fresh weight was known to display its value in the database as if were a dry weight.
That way the reader knows the yields he's viewing are only for dry weights, he doesn't have to mentally shift gears between fresh and dry with each new report, and at the same time the database can capture the more accurate measure of fresh weight when it's available.

 Curb weight - Wikipedia, the free encyclopedia
Curb (kerb) weight is the total weight of an automobile with standard equipment, motor oil, coolant, a full tank of fuel and not loaded with either passengers or cargo.
It is generally provided as a statistic about automobile weights, along with gross weight and gross vehicle weight rating, which represents the weight of an automobile when fully loaded.
The difference between gross weight and curb weight is the total passenger and cargo weight capacity of the vehicle.

 Publication: Corn Grain Yield and Kernel Weight Stability After Black Layer
In most of the studies no changes in kernel dry weight were observed following fl layer; however, in one report, four of 18 hybrids and five of 42 hybrids studied had changes in kernel dry matter as corn dried from 35 percent to about 15 percent grain moisture.
To determine kernel weights in the field dry down/machine harvest method, two 100-kernel grain samples were obtained per subplot for moisture and kernel weight determination and then processed like the hand-harvested samples.
In 1995 kernel dry weights were not affected by either date of harvest or by the storage environment.

 HDCN-- ASN95 Hot Topic -- New techniques for dry weight assessment
Unfortunately there is no standard measure of dry weight and as a consequence it is difficult to ascertain adequacy of fluid removal for an individual patient.
In most centers dry weight is clinically determined and usually reflects the lowest weight a patient can tolerate without intradialytic symptoms and hypotension in the absence of overt fluid overload.
At best this is an imprecise measure of dry weight as it is determined by trial and error and does not account for changes in nutritional status and lean body mass.

 Gross weight - Wikipedia, the free encyclopedia
Gross weight is often confused with curb weight, which represents the weight of the vehicle with no passengers or cargo.
For vehicles containing no fuel or driver, the gross weight is the is the sum of the tare weight (the unladen vehicle weight) and the weight of the load carried.
Such weights are determined by a specialized scale called a weigh bridge, and such scales will usually have a computing function within the display to compute tare weight.

 Obesity In Cats, How To Get A Cat To Lose Weight... Explained In ThePetcenter.com
Dry pet food must have higher levels of flour and sugar than canned foods so that the kibble will stay uniform and not fall apart.
Unfortunately, especially with dry diets, because of the metabolic biochemistry that converts the high carbohydrate content in almost all of today’s commercial cat foods into stored fat, the cat is really at risk for weight gain.
The ability to mobilize fat tissue to be used as glucose for energy (and for subsequent weight loss to be accomplished) requires Carnitine in the process.
