NOZZLE SELECTION OM5560_38#F.1
I
Determine the nozzle size by assuming a supply pressure at 27 bar.
Select from the left column in Table I the nozzle number, which
is
closest to the
calculated nozzle size.
Determine the actual supply pressure.
Note:
If
the calculated supply pressure
is
not within the required limits select
another nozzle size and re-calculated.
If
the result
is
still not acceptable,
consider the actions described in section 1.1.
1.3 Example
Known:
Required oil throughput: 260 kg/h HFO, viscosity
14
cSt.
Required:
The nozzle size and actual supply pressure
1.3.1
Using the
chart
When looking at the left part
of
Figure 2, finding 260 kg/h HFO on the vertical axis,
gives nozzle number: W2-22S and a supply pressure at app. 28 bar. .
