What effect do low viscosity fluids (less than 0.3 cP) have on NPSHR of centrifugal pumps?
Have an insight or suggestion?

Re: Fluid viscosity and NPSHR22 February 2007 at 1:29pmA "low viscosity" fluid would be interpreted as "like water." Therefore, it would have no effect on the NPSHR, as this value is quoted in terms of head which does not change in when the liquid has low viscosities.
