Propagation of sprays with deceleration

The dependence of the maximum height achieved by sprays showing deceleration and stopping at the end of their propagation, on the velocity has been examined. It was assumed that the velocity is greatest at the beginning, so this maximum velocity defines the kinetic energy of each investigated knot at its start. The relation between the maximum height and maximum velocity was examined in 32 knots from 23 sprays. The problem of whether the maximum height achieved by a knot is determined by the gravitational field alone has been studied. The problem of stopping is important especially for knots which have initial velocities higher than the velocity of escape from the Sun.
