I am not sure if I am doing this right, but I am trying to obtain the specific gravity of water at 125 DegF at a pressure of 75 PSIA.
I head over to my steam table, and have two choices, first I use the Temperature column and go to 125 DegF and obtain the ft^3/lb number. I then take the inverse of the ft^3/lb number to obtain the density. I then divide this density by 62.4 (Density of water at 60DegF) to obtain the Specific Gravity.
Or, I head over the Pressure column of the steam table and look for 75 PSIA, then obtain the ft^3/lb number and repeat the steps above.
Each of these yields a different Specific Gravity number, what the heck? What am I missing?
