@cobbly123 The dye was made yesterday and im bottling up the dye now. Were waiting on the arrival of some new bar codes and labels one they arrive ill start making them.
Ricochet J @ Atmospheric is dependent if you in a low pressure area or a high pressure area and since none of us live in the same area the results wouldn't mean much. So i suggest that you buy some liquid and test it out you self. All so you need to take into account that different industry have different base values to work from and "water / Liquid Cooled PCs" do not have a standard. All so we do 50+ different liquids and some contain a slurry which changes things as you should know.
E.g Standard Temperature = 20 °C (68 °F), air density = 1.225 kg/m³ (0.0765 lb/cu ft), altitude = sea level, and relative humidity = 20%.
Air conditioner industry, the standard is often temperature = 0 °C (32 °F) instead.
If you talking about boiling point at these different temps or pressure changes again this all changes and is dependent on were the tests are taken.
But if you after density then if using say X1 concentrate its around 1.02 – 1.26 g/cm3 depending on inhibitors until l you water it down as its a concentrate at which point this will change. The refractive index of X1 is about 1.340.
All if you going into Shear stress in fluids its all dependent as well on many other out lying factors and there would be to many to go into detail on such a subject and im sure no one else except you may care about this.
P.s if your so interested in science and be my guest buy some fluid and play till your harts content.
