Want this question answered?
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 it is true. in the discharge process, water is produced, which dilutes the electrolyte, so reducing its gravity.
rate of discharge
By using refractometer or Hydrometer
1.265
Rate of Discharge
when a battery is fully charged , the amount of sulfuric acid mixed with the water is sufficient to give a specific gravity of about 1.3 when battery is discharged to 50 percent, the specific gravity reading should be 1.2 any specific gravity reading that's less than 1.1 usually indicates a dead batteryThe answer isC. 1.3.
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.
That's a 'hydrometer'.
Known as a hygrometer. May be as simple as a few beads of differing specific gravity in a glass tube with a rubber bulb on top or a complex electronic device that determines specific gravity through measurement of other characteristics. A battery hygrometer uses floating beads to determine the charge of a lead acid battery because the specific gravity of the electrolyte will vary for a given state of charge.
1.250 specific gravity maintenence free battery uses 1.320 gravity
Electrolyte of sulphuric acid to a specific gravity of 1250.
a hydrometer checks the state of battery charge using specific gravity.
