Determining optimal diameter for discharge pipe of pumping station

Abstract

This paper presents a method of determining optimal diameter for discharge pipe of pumping station which is based on the theory of systems analysis and optimization. In the method, the objective function is the lowest total cost, C_tot → Min. A seven parameters formula to determine optimal diameter of discharge pipe was established. The formula was applied for a series of cases of stainless steel pipe in Ha noi region to validate its application. By analysing the effect of the operation duration parameter on the results, it showed that, with the same flow, optimal diameter of discharge pipe depends considerably on the pipe operation duration.
