Common cider making questions!
Each 5° of specific gravity is equivalent to about 1% Alcohol (ABV). To raise the gravity by 5° add about 10 g of sugar per litre of juice. 10g of sugar in one litre of juice will give a potential alcohol increase of 1%. Once you have added your sugar, retest the juice with the hydrometer until the desired specific gravity is reached.

Creep of Posidonia Shale at Elevated Pressure and Temperature
10/08/2017 · The temperature sensitivity of secondary creep with an activation energy Q 3 of about 74 kJ/mol is considerably higher than that observed in the primary regime (≈3–5 kJ/mol). This may reflect a combination of the temperature sensitivity of creep of bitumen with Q between 114 and 175 kJ/mol (Mouazen et al. 2011 ) and of micas with Q = 47 ...
White Wine Making
White Wine Making. The first stage of controlled vinifiion is to crush the grapes and release the pulp and juice, making them easier to press. A key decision at this stage is whether or not to remove the stems. Left with the grapes, stems allow juice to drain more freely during pressing. For some wines, where white wines are being made from ...

Chapter 9: Column Analysis and Design
Short columns fail by crushing at very high stress levels that are above the elastic limit of the column material. Compressive stress for short columns is based on the basic stress equation developed at the beginning of Chapter 5. • If the load and column size ( crosssectional area) are known, the ...
Investigation of lime usage impacts on bauxite ...
11/02/2019 · The settling characteristics of red mud are mostly dependent on bauxite type as well as digestion conditions. Increasing temperature causes finer particles. Lime addition improves the coarseness of red mud even at higher temperatures and enhances settling and autoprecipitation through the red mud washing system [22, 23].
