Abstract

In examination of nonstationary behaviour of pipe networks the knowledge of the pump's dynamic behaviour is a crucial question. In the following an approximate simulation calculation method is intented to be introduced for the examination of pump running out, a transient working state important for practice, where from the knowledge of the t moment state the characteristics of the t+Δt moment state can be determined.
