Why- The lower end of hydrometer is filled with mercury or lead?
The lower end of a hydrometer is filled with mercury or lead because these heavy metals have a high density. This allows the hydrometer to float vertically in a liquid and provide accurate measurements of its specific gravity or density. The heavy metal helps to counterbalance the weight of the stem and bulb of the hydrometer.
What does a hydrometer measure?
Hydrometer measure the density of liquids.
When was the hydrometer invented?
The hydroscope (also called the hydrometer) is thought to be invented by Hypatia of Alexandria. If this is true, the first hydroscope was invented in the 4th century.
Why sea water has a higher hydrometer reading than that of freshwater?
Seawater dissolves more than fresh water because of the salinity in the water.
How do you use a hydrometer?
it is liquid
How does calculated specific gravity compare to the hydrometer reading for the liquid?
The calculated specific gravity may be slightly different than the hydrometer reading. The calculated gravity is calculated using specific data while the hydrometer measures the liquid at a specific time and temperature.
How does the calculated specific gravity compare to the hydrometer reading for each liquid?
The calculated specific gravity may be slightly different than the hydrometer reading. The calculated gravity is calculated using specific data while the hydrometer measures the liquid at a specific time and temperature.
An hydrometer reading of 1.260 - 1.290 means the battery cell is?
fully operational
What is the hydrometer density of diesel fuel reading?
0.84 @20 deg C, but can vary with temperature.
What range of hydrometer density reading of diesel can be used for engine?
you can use range between 0.7500 to 0.8500
What are crude densities?
What is crude densities? Crude densities are measured in api gravity. Api gravity is found by placing a hydrometer in a cylinder of crude at 60 degrees Fahrenheit and reading the depth the hydrometer has sunk into the crude.
What is high grade neuroendocrine carcinoma?
The Ki-67 reading gives the rate of cell proliferation and is detemined by examining tissue samples from the biopsied tumor. A reading of <2% indicates that the tumor is slow-growing. Between 2% and 20% is intermediate grade and >20% indicates a high grade, fast growing tumor.

How does a hydrometer measure density?
It measured by the density of the size from the hydrometer.
Is 7 a high reading?
a high reading for what?
What is the zero correction and meniscus correction in hydrometer analysis?
· Zero Correction (Fz): If the zero reading in the hydrometer (in the control cylinder) is below the water meniscus, it is (+), if above it is (-), if at the meniscus it is zero.· Meniscus Correction (Fm): Difference between upper level of meniscus and water level of control cylinder.
