The relationship between pressure and leakage in water distribution systems has been in the focus of several studies. A common description of the pressure-leakage response is a power equation, or a combination of two different powers like in the fixed and variable area discharge (FAVAD) concept. From a theoretical perspective the exponent can be understood as the result of variable leak opening under pressure and the water flow through the leak channel, which may have different behaviour for specific applications. Thus, these theoretical considerations may explain leakage exponents in the range of 0.5 to 1.5 for turbulent flow. This is known to be contradicted by values from field studies, which measure occasionally higher leakage powers. The understanding of this behaviour of leaks is still...
