Course abstract

Students aquire knowledge of hydraulic machinery – pumps, their use and operating experience. The Course deals with pumping water, sewage, agricultural land drying.

Learning outcomes and their assessment

• Knowledge basics on selection of pumps and designing pumping equipment. Technological solution of pumping equipment. Technological solution of pumping stations.
• Skills of hydraulic computations for selection of pumps, to be competent of tender its, select of pipelines, pipe fittings. To select corresponding accsesories and fitment for flow regulation.
• Competence to make independent analysing og information about pumps, to evalutate selected pump, to justify it for request of environmental protections. .
