Each flowline was equipped with two pairs of "quick closing" valves by means of which the liquid holdup was measured. Transparent nipples were placed at two points in the two inch line and at three points in the four inch line. Through these nipples the flow patterns were photographed. Pressure taps were located at fourteen points in each line enabling the construction of pressure-length traverses for each test run.
