A main steam flow rate measuring instrument uses a steam pressure input to produce main steam mass flow rate indication.
Assuming steam volumetric flow rate does not change, a steam pressure decrease will cause indicated steam mass flow rate to…
A. increase, because the density of the steam has increased.
B. decrease, because the density of the steam has decreased.
C. remain the same, because steam pressure does not affect the mass flow rate of steam.
D. remain the same, because the steam pressure input compensates for changes in steam pressure.
