It contained in the air-dry state nitrogen equivalent to 0.58 per cent.
It has been demonstrated in practice that there is no advantage in allowing sheets to air-dry partially before smoking.
As we have seen, air-dry peat contains 20 to 30 and may easily contain 50 per cent.
It has a green weight, an air-dry weight, a kiln-dry weight, and an oven-dry weight.
The pressing of air-dry peat only succeeds when it is made warm, and is, at the same time, moist.
The yield of cellulose fiber is close to fifty per cent of the air-dry weight of the wood.
For air-dry wood the ratios are considerably lower, particularly in the case of the ultimate strength and the elastic limit.
In composition they differ somewhat by combination with water (of hydration), which they retain in the air-dry condition.
The plants in this process lose about 60 per cent of their green weight, or about 40 per cent of their air-dry weight.
For commercial purposes the weight or density of air-dry or "shipping-dry" wood is used.
