How to use the chart
When inlet pressure (P
) is
1
0.4 MPa, outlet pressure (P
2
is 0.3 MPa, and flow rate is
80 kg/h, first find intersection
point (a) of the inlet pressure
0.4 MPa and the outlet
pressure 0.3 MPa. Trace
down vertically from this
intersection point (a) and find
intersection point (b) with the
flow rate 80 kg/h. Since this
intersection point (b) locates
between nominal sizes 15A or
20A and 25A, select the larger
one, 25A.
