Abstract : In this estimation of impact pressures of a drop with a solid surface, the deformation of the surface of the drop and the onset of post-collisional motion of the liquid are considered. Equations of maximum pressure are developed and their dependence on the extent of wetting of the solid surface shown to be significant. They are not, however, greatly affected by the shape of the free surface formed by the drop on impact. It is also shown how excessive flattening of the drop leads to a reduction of impact pressures.
