A main steam flow rate differential pressure detector was properly calibrated to produce a main steam flow rate indication of 500,000 lbm/hr with the following initial input conditions:
Detector high pressure input = 1,000 psia
Detector low pressure input = 950 psia
The current detector input conditions are as follows:
Detector high pressure input = 985 psia
Detector low pressure input = 935 psia
Assume that the detector and associated circuitry do not have steam density compensation.
Also, assume that the main steam quality and volumetric flow rate do not change.
The current main steam flow rate indication is __________ 500,000 lbm/hr; and the current main steam flow rate is __________ 500,000 lbm/hr.
