Re: Why Do We Use The Term Specific Gravity?
I don't use specific gravity, I use density
The difference is only moving the decimal point around if you work in metric
So what you use is totally trivial

Re: Why Do We Use The Term Specific Gravity?
Dear babasri09,
Have a look at:
http://en.wikipedia.org/wiki/Relativedensity
Specific gravity is measured by a hydrometer and a pycnometer.
These instruments measure the density in relation to a specific (for the experiment) used liquid F.i. oil for cement, which would react with water)
After the experiment, the real density can be calculated on basis of the real density of the used liquid.
That is all.
Specific gravity (or relative density) is only used in bulk conveying when the material density of a product has to be measured.
Have a nice day

Specific Gravity is a non-dimensional term and therefore useful for those who still use the archaic avoirdupois system of units and similar exercises in mental arithmetic. ■

Pot Of Gold
How many bushels in a calderkin, how many calderkins in a room and how many litres in a barrel?
Remember the old scam when the gold price was floated in the early 70's and some Jack the Lads were flogging 'genuine' Kruger Rands weighing one ounce for a few bob below the regular price. The gold was there right enough but the official price of gold was for a troy ounce which is a few grams heavier than the avoirdupois ounce which Jack the Lad was touting; and perfectly legally.
"i've got you over 621 litres!" doesn't sound right though. Maybe it's a troy barrel.■

Re: Why Do We Use The Term Specific Gravity?
We use specific gravity to show what specific gravity is required to be compatible with operation of our float switches.
Water has a SG of 1, our floats have for example 0.7 which means they float in water. ■
Why Do We Use the Term Specific Gravity?
I want to know, what is the reason we use the term specific gravity,instead of density for liquids?
i don't want the definition of specific gravity. ■
