What should be Specific gravity at 15°C if observed SG is 0.834 of HSD
To determine the specific gravity at 15°C if the observed specific gravity is 0.834 of HSD (High-Speed Diesel), you would first need to find the specific gravity of HSD at that temperature.
The specific gravity of HSD varies depending on the temperature, so you would need to refer to a specific gravity chart for HSD at 15°C. Once you have the specific gravity of HSD at 15°C, you can calculate the specific gravity for the observed 0.834 ratio.
For example, if the specific gravity of HSD at 15°C is 0.85, you can calculate the specific gravity for the observed 0.834 ratio by multiplying the specific gravity of HSD by the observed ratio:
Specific gravity = 0.85 * 0.834 = 0.7089
Therefore, the specific gravity at 15°C would be approximately 0.7089.
