Abstract
This report summarizes the results of work performed for US Army GVSC by the National Institute of Standards and Technology (NIST), Applied Chemicals and Materials Division on the development of a computer program for fire-suppressant bottle-filling calculations under interagency agreement number 11478007. The work includes the development of a spreadsheet that is to be used with the NIST23 (REFPROP) to provide two bottle-filling calculations (1) given vessel size, mass of agent, mass of pressurizing agent, and filling temperature compute the filling pressure, and the temperature and pressure conditions at which the fluid in the vessel becomes single phase, and (2) given the vessel size, mass of agent, and filling temperature and pressure, compute the mass of pressurizing fluid, and the temperature and pressure conditions at which the fluid in the vessel becomes single phase. The agents include CF3I, R-218, R-125, R-227ea, R 13B1, R-236fa, HFE-7100, Novec 649 (also known as Novec 1230 and FK-5-1-12)), R 1233zd(E), R-1336mzz(Z), and R1336-mzz(E)). Two pressurizing agents are available, nitrogen and carbon dioxide. There also is an option to include solid sodium bicarbonate powder in the calculations, and the ability to generate tables of conditions in the vessel as a function of temperature summarized with simple graphics.Citation
