c_300_recycle_scfm for HRS18006At 18006 there are two flow paths from the TK700 that are used to recycle flow back to the C300 compressors inlet at TK100 . We can calculate this flow rate using the flow meters.
FT_101A measures flow entering Tk_100
FT_202 measures flow entering the C300 compressors
fcv_102_scfm measures the flow of gas lost in TK_100
c_300_recycle_scfm = FT_202 - FT_101A + fcv_102_scfm
