Outlet cross-section

The outlet cross-section of the system is an agreed cross-section in the discharge-side piping or in another space on the discharge side with known geometric and flow data. A distinction must be made between a system (e.g. pump system) and a pump. The outlet cross-section of a pump is identical with the cross-section of the pump discharge nozzle. If there is no discharge nozzle the pump's outlet cross-section must be defined, e.g. the cross-section at the end of the discharge elbow. See Fig. 2 Head
