The specific gravity of the oil can be determined by comparing its density to that of water. Since the density of water at 10 degrees Celsius is given as 1000 kg/m3, we can find the specific gravity of the oil by dividing its density by the density of water.
Let's assume that the density of the oil is ρ (in kg/m3) and its specific gravity is SG. The specific gravity can be calculated using the formula:
SG = ρ / (density of water at 10 degrees Celsius)
Now, let's move on to determining the pressure reading on gage C. In a closed tank with Bourdon-tube gages tapped into it, the pressure readings on the gages are proportional to the liquid column height above the gage. This is because the pressure in a fluid increases with depth.
Since gage C is tapped into the tank, the pressure reading on gage C can be determined by finding the height of the oil column above gage C and converting it into pressure.
To find the pressure, we need to know the height of the oil column above gage C and the density of the oil. Once we have this information, we can use the formula:
Pressure = density of the oil * acceleration due to gravity * height of the oil column
By substituting the given values, we can calculate the pressure reading on gage C.
Remember to double-check the units and make sure they are consistent throughout the calculation. Also, keep in mind that this explanation assumes the gages are calibrated and accurate.
