The weight of dry, seasoned Oak depends on it's type (English Oak, Red Oak Cork Oak etc), but will be in the range of 590 to 930 kg/cubic metre. This is an enormous variation, but there are lots of varieties. To convert kg/m³ to lbs/cu ft divide by 16.01846. If you know the specific type of Oak you are working with, the answer can be more precise.
2 pounds
If from dried wood, approximately 550 to 600lbs. If from undried hardwoods, approximately 750 to 800 lbs.
At one time, sawmills cut green lumber to 2"x8". A higher-humidity board would shrink more than an dryer board, and in any case, the board would be reduced in size by planing (smoothing the rough-cut sides.) Seems to me that the industry standardized the size of wood about 40 yeas ago. Now, sawmills calculate the size to cut so that dried and planed wood will be a standard size when dried. A 2x6 is actually 1.5 inches thick and 7.25 inches wide.
Dried clay
Dried leaves are dead leaves.
There is approximately 0.424 pounds of lentils in one cup. This means that there would be about 10.588 pounds of lentils in 25 cups.
A cubic foot of red oak weighs 44 lbs kiln dried to 6%, appx 61 lbs wet. One cubic foot of wood equals 12 board feet of lumber; 1" x 12" x 12" times 12.
Kiln dried Red Oak at 6 percent moisture content weighs 4.444 ounces per cubic inch WRONG! 4.444 ounces per cubic inch is off by a factor of 10. It should be .4444 ounces per cubic inch
King Henry VII was the one who defined a pound as the weight of 7,000 dried grains of wheat.
The oven-dried weight of 8.66 tons (7.86 tonnes) is the mass -- which varies by species -- of a 78.41-foot- (23.9-meter-) tall, 15.5-ton (14.38-tonne), 222-year-old oak tree in the OneOak project through the Sylva Foundation. That represents a 58.39-foot- (17.8-meter-) diameter crown oven-dried weight of 4.88 tons (4.43 tonnes) and a 35.35-inch- (89.8-centimeter-) tall main trunk oven-dried weight of 3.78 tons (3.43 tonnes). The mass of oak wood tends toward 1,300.73 to 2,050.3 pounds per cubic foot (590 to 930 kilograms per cubic meter).
A dried fruit will weight less than one that isn't dried (both of the same size and shape).
If from dried wood, approximately 550 to 600lbs. If from undried hardwoods, approximately 750 to 800 lbs.
It depends upon the species as weights can very greatly, even among softwoods, such as pine, fir, or especially cedar or cypress. Additionally, moisture content and treatments can impact the finished weight. Southern Yellow pine, fresh cut varys from 36 lbs/cubic foot (20% moisture) to 53 lbs/cubic foot for fresh cut (green). Pressure treating also adds additional moisture, thus weight. If the lumber is from a lumber yard, not treated, kiln dried, dimensional pine lumber would typically weigh 37 lbs / cubic foot, so a 16' 2 x 4, actually 16' 1.5" x 3.5" would be: 1.5 X 3.5 X 192 = 1008 cubic inches 1728 cubic inches in a cubic foot so: 1008 / 1728 = 0. 583 cubic feet weight of pine = 37 lbs/cubic foot X 0.583 = 21.58 lbs for a 16' 2" x 4". or 1 1/2" = 0.125 cubic feet 3 1/2" = 0.292 cubic feet .125 X .292 X 16 = 0.583
not really but it depends
Yes, due to the water leaving the fruit, it does in fact lose weight.
2.5 kg 20 kg fresh grapes will contain 2 kg of grapes and 18 kg water. In dried grape, grape concentration is 80%; that implies 2kg should be taken as 80%. So, total weight of dried grape is 2.5kg.
In the U.S., a dried plum used to be called a prune. The California Plum Board requested a name change when research showed that "prune" had a negative impact.
On long journeys, people ate low-weight, high caloric foods. These were dried meats, dried fruits, seeds and nuts.
