Specific Gravity
Specific Gravity
(OP)
Hi all,
Specific Gravity is defined as (density of fluid) / (density of water @ 4degC & at 1atm).
Does the 'density of the fluid' of interest have to be at the same temperature of that of water (i.e. 4degC) to get an accurate specific gravity figure. I think it does and my calcs kinda prove it, but the internet is full of contradictions, just just wanted to check here if anyone knows for certain
Sames goes for specific density of gas .... whether the density of gas has to be at the same temp and pressure as the reference density of air at STP

RE: Specific Gravity
But - it depends on your use. If you means does is specific density is a reference density that is at Standard Temperature and Pressure or if it is the specific density at the instant of interest. The first will be in a text or other reference book, the second will not.
