Recent experiments make it appear more likely that the order parameter of the unconventional superconductor Sr2RuO4 has a spin-triplet f-wave symmetry. We study ultrasonic absorption and thermal conductivity of superconducting Sr2RuO4 and fit to the recent data for various f-wave candidates. It is shown that only fx2−y2-wave symmetry can account qualitatively for the transport data.
