Assume an 8-inch schedule 160 pipes (ID = 6.813 inches) carries a full flow of 40,000 pounds per hour of dry saturated steam. The static pressure is 335 psi. Flange taps are used and the differential pressure across the orifice plate at the full-flow rate is 100 inches of water. What is the size of the bore in the orifice plate?
A. 4.357 inches
B. 3.645 inches
C. 2.271 inches
D. 5.109 inches
