Abstract
WHEN the water-hammer surges that accompany rapid velocity changes in pipes are of such a kind as to produce a fall to vapour pressure, cavities are formed. Theory and analysis at present available rest largely on empirical evidence of changes in pressure alone. In the case of rupture, a recent publication appears to support methods of analysis already in use1, and suggests cavity formation would take place at the control (gate) end of a straight horizontal pipe.
