By assuming a uniformly converging radial flow on the upstream side of an orifice and integrating the equation of motion, an expression was derived to estimate elongational stresses for dilute polymer solutions at the orifice exit from pressure drops between the upstream and downstream of the orifice. The expression shown that the dilute polymer solutions usually give lower values of pressure drop than the solvent (water) does. An experiment was carried out to obtain the pressure drops for the orifice flow of water and dilute polyethylene exide (PEO)-water solutions. It was confirmed that the dilute PEO solutions yield lower pressure drops than water and the elongational stresses were estimated by the above-mentioned relation. The estimated elongational stresses broadly agreed with the ones previously obtained by a jet thrust method.
