what is the density of nitrogene @ 1.02 bara?

Answer 1

One bar is based on the pressure the atmosphere exerts at sea level, about 1.02 kg per sq cm, or 14.7 lb per sq in.

Specific Gravity:
Nitrogen - N2 (pure) 0.9669

Nitrogen - N2 (atmospheric) 0.9723

The density can be expressed as
ρ = m / V = 1 / vg (1)
where
ρ = density (kg/m3)
m = mass (kg)
V = volume (m3)
vg = specific volume (m3/kg)

I hope this helps you. I tried to do a search using many terms. And this is the best information I could come up with.

Answer 2

Strictly speaking, you need to know the temperature as well as the pressure. Nitrogen has a molecular weight of 28, so an Avogadro standard volume (22.4 liters) weighs 28 grams under standard conditions. The slightly elevated pressure isn't enough to worry about other than to keep your instructor happy, so do the obvious division and call it good.

Answer 3

You will get the best and authentic data on the web from http://webbook.nist.gov/chemistry/fluid/

At 25C and 1.02 bara the density is 1.1529 kg/cu.mtr

Answer 4

0.97226 Kg/m³
