 note = {The discharge coefficients of three orifices, that is, straight, quadrant-edged and sharp edged
orifice, in a commercial 1-in. gas pipe for pseudo-plastic　fluid (carboxymethyl cellulose
aqueous solution) were measured. The concentrations were 0.20, 0.35　and 0.49 in
wt%, and the throat area ratios of these orifices were roughly 0.39. The results obtained
were shown as follows :
1) For the laminar flow region, the log-log correlation of pipe friction factor and pseudo-plastic
Reynolds number Re_psu coincided with that of Newtonian fluids.
2) Within the range investigated, the allowable limit of Reynolds number for each orifice
did not depend on the concentrations.
In the region above the allowable limit of Reynolds number, the relation between the
discharge coefficient for each orifice and Re_psu was independent of the concetrations.},
