13.2 Curve conditions
The guidelines below apply to the curves on the next 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).
