Turbulent equations are derived by transforming Euler equations. In this equation, the concept of “virtual optimal working conditions” is proposed. Turbulent flow regimes are separated before and after the runner. Turbulence losses are calculated using the energy characteristics of the turbine. In order to determine the risk of stable operation
