Recording characteristic curves of industrial fittings and a centrifugal pump
Features
– plotting characteristics of industrial valves and fittings
– comparison of different valves and fittings
– characteristics of a centrifugal pump
Learning objectives/experiments
– characteristics of a centrifugal pump
– behaviour during operation and function of
