MetadataThis section provides information about 'RDS402884'.

DefinitionA <SUCTION SPECIFIC SPEED> is an <INDEX NUMBER> for a <CENTRIFUGAL PUMP>. It relates flow rate, NPSHR and rotation speed for pumps of similar geometry, calculated for the pumps performance at best efficiency point with the maximum impeller diameter. nqs=(N*(Q^0,5))/(NPSHR^0,75) where; nqs=suction specific speed, N=rotation speed in revolutions per minute, Q=flow per impeller eye in cubic meters per second (half flow for double suction impellers), NPSHR=net positive suction head required in meters
