description In this study, the effects of the blockage of the intake pipe and impervious flow boundaries on critical submergence of an intake are presented. The potential solution based on the Rankine stagnation point is found to be an approximate method for the prediction of the critical submergence for an intake pipe. It is found that a critical spherical sink surface with a radius equal to the radial distance of the stagnation point (which is 1/ times the critical submergence of the intake) can also be used to predict the critical submergence. The agreement between theoretical results and available experimental data indicates that this critical spherical sink surface gives good results especially for the intake when the distance of the impervious vertical dead-end wall to the center point of the intake is smaller than or equal to the diameter of the intake.
