Fuel gas is carried in a 6-inch schedule 40 pipe (ID= 6.065 inches). The flow rate is measured with an orifice plate using flange taps and the bare in the orifice is 3.457 inches. The specific gravity is 0.88, the flowing temperature is 60 °F, and the static pressure is 25 psi. Maximum flow rate creates a differential of 20 inches of water. What is the approximate flow rate in cubic feet per day?
A. 1,500,000 SCFD
B. 2,000,000 SCFD
C. 2,500,000 SCFD
D. 3,000,000 SCFD
