The following is the current calibration data for an orifice plate that is being used for water flow rate measurement:
Upstream Pressure = 135 psig
Downstream Pressure = 120 psig
Flow Rate = 100 gpm
During a surveillance, the following pressures are observed across the orifice plate:
Upstream Pressure = 124 psig
Downstream Pressure = 117 psig
What is the approximate water flow rate through the orifice plate?
A. 47 gpm
B. 57 gpm
C. 68 gpm
D. 78 gpm
