Refer to the drawing of four identical tank differential pressure (D/P) level detectors (see figure below). The tanks are identical and are currently at 2 psig overpressure, the same constant water level, and a temperature of 60°F. They are surrounded by atmospheric pressure. All level detectors have been calibrated and are producing the same level indication. If a leak in the top of each tank causes a complete loss of overpressure, which level detector(s) will produce the lowest level indication? A. No. 1 only B. No. 2 only C. No. 1 nd D.
