where apdc = downcomer pressure drop, Ibf/ft2

Ptr = density of aerated liquid on tray », lbm/ft3

H'th = height, feet, of aerated liquid on tray just downstream of inlet weir

Pn+i = pressure, lbf/ft2, above liquid on tray n + 1; P„ is pressure on tray n

Note that we assume that poc does not vary.
