The results indicate that biodiesel and its blends demonstrate temperature-dependent behavior that is qualitively similar to the diesel fuels. 5 / (API + 131. Measure the specific gravity of your wort, take the temperature and add the correction (Delta G) value given in the table. This is done to get a better understanding of the grain-size distribution and percentage of silt and clay in a sample soil. • The hydrometer and the suspension now weighed in the liquid for some specific value i. 8° C), the specific gravity would be (1. 3 and Table 3. Note: that what ever units your hydrometer is calibrated in, the solution to be measured for its density needs to be at the temperature the hydrometer was calibrated or standardized at, adjustments or corrections for different solution temperatures will need to be made. The hydrometer test is performed by testing a soil sample that was allowed to pass through a number 10 sieve size. Know the temperature at which your hydrometer works. Otherwise, use a value of 2. 03×Temperature - 1. Propylene Glycol cannot be read with a hydrometer due to the fact that up to 70% concentration specific gravity increases, but above 70% specific gravity decreases. The temperature correction is concentration dependent and therefore it is recommendedto measure at the desired temperature, if possible. In view of the extensive use of hydrometers at tanneries, The Ameri­ can Leather Chemists Association suggested that the National Bureau of Standards check the barkbmeter correction table in most common. 7° C (+20° F) might read 1. A lower temperature leads to a higher estimate of the density of the product which, if the correction is disregarded, is to the disadvantage of the filler (producer). Table 53B (Order Part No. 0 90 Chase Salometer Freezing & Temperature Correction Guide. Then chill a sample of your wort and measure the gravity with a hydrometer. For known G s of the soil (if not known, assume 2. When using any hydrometer, it is important to note and record the temperature at which the brine solution is measured and then do a manual calculation to compensate for temperature differences between the temperature at which the salt brine solution was measured and the reference temperature of the Salometer. Tanaka et al. The solution was stirred vigorously for several minutes to eliminate thermal and compositional gradients.
