The general validity of the first‐order fluid model is considered. Conditions are established for which a first‐order fluid represents an acceptable approximation to the integral viscoelastic fluid from which it was derived as a Taylor series approximation. The results are applied to two flow problems: generation of flow by the application of a pressure gradient and the growth or dissolution of bubbles in viscoelastic liquids. © 1999 John Wiley & Sons, Inc.
