B. Engine Air Flow Rates
(1) Testing parameters
(a) Air: clean and dry.
(b) Pressure: 19.8 psi (137 kPa).
(c) Temperature: 68 deg.F (20 deg.C)
(2) The air flow rates of each engine oil circuit is given in the table 202 below, in these conditions:
(a) The test rig must be selected to the large size selector: 0.18 in. (4.6 mm) diameter, for the forward engine sump.
(b) The test rig must be selected to the medium size selector: 0.13 in. (3.3 mm) diameter, for the rear engine sump and for the AGB/TGB.
