7. Qstd = .6776261[2.4035659 + .00613]
8. Qstd = .6776261[2.4096959]
9. Qstd = 1.632
Throughout these example problems you may find that your answers vary
some from those arrived at here. This is probably due to different calculators
carrying numbers to different decimal points. The variations are usually slight
and should not be a point of concern.
With the Qstd determined, the corrected manometer reading (FLOW
(corrected)) for this run point needs to be calculated using the following
FLOW (corrected) = [Sqrt("H2O)(Pa/760)(298/Ta)]
FLOW (corrected) = sampler manometer readings corrected to current
Pa and Ta "H2O = sampler manometer reading
during calibration
Pa = ambient barometric pressure during calibration, mm Hg.
760 = standard barometric pressure, a constant that never changes, mm Hg
Ta = ambient temperature during calibration, K (K =273 + Celsius)
298 = standard temperature, a constant that never changes, K
Inserting the data from run point one from the calibration worksheet (two
manometers) we get:
FLOW (corrected) = [Sqrt(5.4)(757/760)(298/293)]
FLOW (corrected) = Sqrt(5.47047)
FLOW (corrected) = 2.3389035
