Thank you dcasto. Please clarify few things on the equation you posted
What are: sggr and spgr
I see that the equation is not temp consistent. Both F and R are used. Is this correct?
Is volume (last term in equation) the tank volume?

How do i go about calculating the total mass of LPG (mixture butane-propane)in a tank which contains both liquid and gas phases.
Given data are: Total tank volume, liquid level, total pressure and tank temperature.
Any input will be appreciated.

I have a question regarding a calculation using the section 11.1.7.2 routine of API. I have more details in the attachment.In short, no matter what I have tried I cannot get the results of the routine to agree with those of table 53B when the "Transition zone" Ks are used.
