Aluminum has no specific gravity, at least by the current definition of gravity.
specific gravity of fly ash is 3.2
Specific gravity doesn't have units. It's the density relative to water, so specific gravity is effectively just a number.
"Specific gravity" or "specific density"
Every substance has a specific gravity. Aluminum's is around 2.6 .
Yes, that is true. As a battery discharges, the concentration of sulfuric acid in the electrolyte decreases, leading to a decrease in density or specific gravity. This change in electrolyte density can be used as an indicator of the state of charge of the battery.
To check the specific gravity of a battery, you will need a hydrometer. Remove the battery caps and draw some electrolyte into the hydrometer. Compare the reading with a chart to determine the specific gravity, which will indicate the state of charge of the battery.

A hydrometer is commonly used to test the specific gravity of a forklift battery. This device measures the density of the electrolyte in the battery, which can provide information about the state of charge and health of the battery.
Rate of Discharge
When an automotive battery is fully charged, the sulfuric acid and water mixture will have a specific gravity ranging from 1.265 to 1.285. This specific gravity indicates the concentration of sulfuric acid in the electrolyte, which is an important factor in determining the battery's state of charge.
If the specific gravity of a forklift battery is not increasing, it may be due to a few reasons such as insufficient charging time, sulfation on the plates, or inadequate electrolyte levels. It is important to ensure that the battery is properly charged, water levels are maintained, and the battery is properly maintained to allow for proper specific gravity readings.
The discharge time of a battery depends upon its Ah. capacity, Load current & rate of discharge. If a 150Ah battery rated for 10hours is discharged at 15A rate it should last upto 10 hours if the temperature and specific gravity of the electrolyte (in case of flooded type batteries) are within specified limits. If the same battery is discharged at 12.5 A it will last upto 5hours. 1. As the discharge rate increases the capacity of battery decreases. 2. As the temperature increases the capacity of battery increases.
When an automotive battery is fully charged, the sulfuric acid and water mixture will have a specific gravity of around 1.265 to 1.275. This specific gravity measurement indicates the concentration of acid in the electrolyte, which is crucial for the battery's performance and capacity. It is important to regularly check and maintain the specific gravity of the electrolyte in a battery to ensure optimal functioning.
Specific gravity of a lead acid cell measures the density of the electrolyte solution in the cell, which can indicate the state of charge of the battery. A higher specific gravity typically corresponds to a fully charged cell, while a lower specific gravity may indicate a discharged or faulty cell.
