| Abstract: | A mathematical model for calculation of the maximal start_up head of pumping stations is developed by use of the principle of aerodynamics. The theoretical result, including head and discharge of the pump and air pressure in the outflow conduit during the start_up, accords with the experimental one, which shows that the method proposed is correct. At the same time, the conclusions and suggestions obtained are of importance to the optimum design and economical operation of pumping stations. |
