The theory of drop deformation in steady elongational flow is extended to the non‐steady elongational flow in a converging cone, Experiments with different fluid viscosities were carried out and compared with the theory, which is valid only for low deformations. The theory describes the drop deformation satisfactorily and under certain conditions even for higher deformations than expected.
