One of the simulated trajectories of event 3 with varying flow velocities derived from a theoretical equation (Eq. 1). The input ejection velocities \(v_{x}\) and \(v_{y}\) are calculated based on the observed trajectory. A drag coefficient (CD) of 0.8 and a particle diameter of 20 cm are used. The mean drag coefficient value of 0.8 is based on the measurements of Alatorre-Ibargüengoitia and DelgadoGranados (2006)
