Abstract
High viscosities (low Reynolds numbers) impair the pump performance. Liquids with up to ν = 3000 mm2/s (3000 cSt) can be pumped with centrifugal pumps, but efficiencies drop to very low levels which make the operation highly uneconomic.

The term “oil” in the following text is meant to include all highly viscous fluids.
- 2.
This equation covers the whole range from laminar to fully turbulent flow.
- 3.
This can be verified by inserting into Eq. (T13.2.1) Q ~ n × d3 and H ~ n2 × d2 and \( Re\, \text{~} \, n \times d^{2}/\nu \) according to the similarity laws listed in Table 3.4.
- 4.
Compare this process to water films forming on the blades of wet steam turbines.

Maximum tip speed in these tests was 86 m/s. The first group of 8 stages had impeller diameters of 250 mm, the last 5 stages were 232 mm.
- 7.
In [38] a (quite unrealistic) exponent of 2.46 for the specific speed was derived from tests with nq = 27 and 30. Considering the scatter inherent to this type of measurement, it appears unwise to attempt on so narrow a test range to determine an exponent for extrapolation to situations outside the tested range. The calculations in [41] produced a more plausible exponent for nq.
- 8.
Equation (T13.5.14) was derived from a graph in [49]; it is valid for particle diameters greater than 0.5 mm. With smaller particles the critical velocity is lower than predicted from Eq. (T13.5.14).
