...) is applied to estimate the transient measurement uncertainty and compared with the Taylor series method (TSM). The systematic uncertainty of the flowrate calculation is equal to the standard deviation of the probability distribution of the flowrate. The flowrate probability distribution from the pressure...

... rig attains Reynolds number based on a throat diameter up to 1.4 × 10 7 , and the uncertainty of the reference flow rate is about 0.1% so that the behaviors of the discharge coefficients versus the Reynolds number can be investigated clearly. The measurements of the discharge coefficients with several...
