* Pump leakage: This fault results in a leakage mass flow downstream of the pump. It is modeled with an additional valve which can be opened and thus inject a partial mass flow into the environment. The opening area of the valve $A_{\text{valve}}$ is a linear function of the throat are $A_{\text{0}}$ and the position of the valve $x_{\text{valve}}$\
