Why NPSHR Changes With Impeller Diameter?
Written on February 1, 2011 at 10:43 pm, by Joe Honeywell
Introduction Confusion sometimes results when reviewing published NPSHR curves. This is especially true when faced with trimming the impeller diameter to match changing operating conditions. A well known fact is that the head-flow relationship varies with the diameter. This can be accurately approximated by the affinity laws. However, what happens to the NPSHR-flow relationship whenContinue Reading
