Density of H20 @ 150 C & 600 psi pressure
Density of H20 @ 150 C & 600 psi pressure
(OP)
Can anyone please show me how to look up Density of H20 @ 150 C & 600 psi pressure (Co2)....
I found a water table which shows 916.69 kg/m^3 but it does not show anything @ pressure. Isnt density related to both pressure & temp.?
What would be the difference in density if No gas was there and is gas was there?

To answer your basic question, as long as water is water, the change in density with pressure is very small (on the order of 0.002 volume reduction per 1,000 psi). So you go to the water table, find the temperature you are looking for, verify that the pressure is above the saturation pressure for that temperature, then use the density on the table.
I truly don't know what to do with your last statement since the gas discussion is so muddled in your post.

The NIST site has a Java script that didn't run for me. I bought REFPROP from NIST a couple of years ago and it is really stable. It gave me 0.91925 g/cm^3 which is 0.1% higher than I got from Cameron. The water tables seem to be way close enough for Engineering analysis.

But we don't know what you need the density for, and what your accuracy requirements are. Putting 600 psi CO2 above the water will cause the slight compression zdas04 has noted, but CO2 dissolved in the water will affect the density too. I guess it will increase the density, but I do not have any data (more accurately - I am too lazy to look for any). For normal engineering work I would ignore this change and use figures like zdas04 has given. But only you know what degree of accuracy you need.

If CO2 is indeed "acting" on top of water, one shouldn't overlook the resulting water acidity level.
