Abstract

This paper presents an experimental setup and measurement of pressure coefficient on a static model of an irregular shape building with pressure taps mounted on it, in a boundary layer wind tunnel. The building is the future sports hall in Oradea and it will be 23,05 m heigh. This research helped the civil engineers in the design process of the envelope and the structure itself because the design codes do not contain all forms of buildings, especially the irregular ones.

4. REDUCING ENERGY CONSUMPTION BY UPGRADING PUMPING STATIONS IN WATER DISTRIBUTION SYSTEMS.

Author

Perju, Sorin and Hasegan, Liviu Valer

Abstract

Adjusting the operating parameters of pumping stations equipped with fixed speed pumps is achieved by manipulating the valves from the pumps' discharge. In order to meet the requirements of the distribution networks, the pumps are being strangled at startup and they remain so throughout the entire period of operation. This paper presents a method developed to estimate the energy costs in a pumping station operation, based on an analysis using the data recorded in the register of the station operation.
