The measuring methods available for obtaining pump performance are examined in the light of experience obtained at the National Engineering Laboratory (N.E.L.). Consideration is given both to experimental procedure and to the interpretation of results.
Since it has been found that pump performance can be markedly influenced by installation conditions, some typical effects are examined.
