An attractive technique for measuring elongational viscosity developed in previous works, has been generalized and evaluated using numerical simulations. The technique involves extruding a material through a cylindrical, semihyperbolically converging die. The analysis of the flow equations is generalized to use less restrictive assumptions than reported in previous studies.
