| 21. | They are usually light in color and have specific gravities less than 3.
|
| 22. | Hydrometers are used to calculate the specific gravity of a battery.
|
| 23. | The Original Gravity is the specific gravity measured before fermentation.
|
| 24. | The specific gravity of bytownite varies between 2.74 and 2.75.
|
| 25. | :And therefore specific gravity = submerged height / total height.
|
| 26. | This formula gives the true specific gravity i . e . based on densities.
|
| 27. | High specific gravity is a diagnostic property of a mineral.
|
| 28. | In British brewing practice the specific gravity as specified above is multiplied by 1000.
|
| 29. | The hardness is 3, and the specific gravity is 4.3.
|
| 30. | Consider hardness test, streak test, specific gravity, borax bead test.
