15.2 Curve conditions
The guidelines below apply to the performance curves on the
following pages:
• Test liquid: airless water.
• The curves apply to a density of
ρ
= 983.2 kg/m
3
and a liquid
temperature of +60 °C.
• All curves show average values and should not be used as
guarantee curves. If a specific minimum performance is
required, individual measurements must be made.
• The curves for speeds I, II and III are marked.
• The curves apply to a kinematic viscosity of
υ
= 0.474 mm
2
/s
(0.474 cSt).
