It was determined that droplets do not reach terminal velocity before a typical impact, raising the question of how to predict impact velocity. This question was investigated experimentally, and the results were used to validate a theoretical model. Experiments used droplets with diameters 0.70mm to 4.0mm, liquids with a density of 791kg/m3 to 1261.5kg/m3, and viscosities 1.0mPa s to 1390.0mPa s, release height up to 1.0m. The ambient pressure was varied between atmospheric and 25kPa. It was shown that th","authors_text":"Jiguang Hao, J. M.
