Further to the thread 'where is everyone' in the industrial sector, I write to forward some information on CO2. I was, shall we say, engaged in some friendly banter with Marc about this topic, who was requesting info on the subject.
Anyway, to cut a long story short, I have not been able to log on for a while, but now I have the chance and after consulting the Ashrae manuals, I have the information required.
P.S. let marc know that he was right about obtaining the info, yes, I did have to refer to various literature - after all, this is 'new technology', and is very much in it's infancy. He would probably have to do the same if I asked him to quote me specific info on methyl chloride!!!!!! Anyway here goes: -
Triple Point Temp: - 56.57 Degrees C
Info @ TP: Absolute Pressure = 0.518 MPa; Density of
liquid = 1178.3 m3/kg; Vapour Volume = 0.072 m3/kg; Enthalpy (kj/kg) Liquid
= 80.48
Vapour = 431.10; Entropy (kj/kg/k)
Liquid = 0.522 Vapour = 2.141; Specific Heat Content (kj/kg/k) Liquid =
1.995 Vapour = 0.859
Thermal Conductivity (mW/m/k) Liquid =
180.6 Vapour 11.30
Critical Point Temp: 30.98 Degrees C
Conditions @ 20 Degrees C
Absolute Pressure = 5.727 MPa; Density of
liquid = 773.3 m3/kg; Vapour Volume = 0.00514 m3/kg; Enthalpy (kj/kg)
Liquid = 255.91
Vapour = 407.57; Entropy (kj/kg/k) Liquid
= 1.1879 Vapour = 1.7052; Specific Heat Content (kj/kg/k) Liquid = 4.259
Vapour = 4.585
Thermal Conductivity (mW/m/k) Liquid =
87.2 Vapour 34.19
I hope people that are interested will find the above informative, If anyone
requires PH charts or any further info, my Email No is PStacey859@aol.com.
PS As the previous thread is now closed, can you distribute this info to all concerned.
Thanks
