    Leak Rate Equations. Leak Rate Leaks are common occurrences in pipes, tubes, and tanks. The leak rate is based on the pressure difference between the inside and outside of the pipe, the crack or hole area, and specific gravity of the liquid. The pipe leak rate calculator computes the leak rate of a liquid out of a circular or non-circular crack or hole in a pipe or tank.
