A nuclear power plant is initially operating with the following main steam parameter values:
Main steam pressure = 1,000 psia
Main steam flow rate = 500,000 lbm/hr
Main steam pressure decreases and stabilizes at 950 psia.
Assume 100 percent quality saturated steam and that main steam volumetric flow rate is the same before and after the pressure change.
Which one of the following is the approximate mass flow rate of main steam after the pressure change?
A. 528,000 lbm/hr
B. 500,000 lbm/hr
C. 472,000 lbm/hr
D. 444,000 lbm/hr
