I recall taking water flow tests in Oz using the zero foot rule.
We used the same hydrant for static and residual, but the measurement tool
had more dimensions than just a pitot gauge.
I don't think the water knows the difference, even if we make a
distinguishment.
If the flow is fully developed and turbulent, the error in the gauges can
be more than the error from the time-average owing to turbulence.
A robust flow test might then take the square root of the sum of the
squares of each estimated-error term {gauge error, variability in
turbulence error, etc.}.Scot Deal Excelsior Risk and Fire Engineering gms: + 420 606 981 266 -------------- next part -------------- An HTML attachment was scrubbed...
