FLOW RATE RANGE [Table1]
¡Liquid
Retain the minimum flow rate in Tables A (according to specific gravity) and B (according to viscosity), whichever is the
greater.
Table A (according to specific gravity)
¡Gas
The flow rate range is indicated in actual base.
If the flow rate was given at standard status, be sure to convert it to actual flow rate and then, according to this table,
determine the flow rate range or nominal diameter.
™Determination of minimum flow rate
In Table D, find a value that is nearest to and lower than
the pressure of gas desired, trace it upward in the same
column, and retain the value at the intersection with the
desired nominal diameter in Table C as minimum flow rate.
If it is necessary to exactly determine a minimum flow rate,
proceed to a calculation in the following manner.
Example 1
From Table C, the minimum flow rate at density of 6 and
nominal diameter of 80 mm is 47 m
density of 11, is 38 m
the minimum flow rate is, according to interpolation,
Nominal

Suppose the fluid is air, the temperature 20 C, the pres-
sure 0.5 MPa (gauge), and the nominal piping diameter
80 mm. How can the minimum flow rate nominal diam-
eter be found?
The minimum flow rate at nominal diameter of 80 mm at
air of 0.4 and 0.85 MPa in Table D is, according to Table
C, 47 and 38 m
MPa, therefore, the minimum flow rate is, according to
interpolation,
Or the minimum flow rate can be obtained upon calcu-
lating an actual density.

rate and the applicable nominal diameter be found? First
obtain the actual maximum flow rate, and then deter-
mine the nominal diameter. For calculating the maxi-
mum flow rate when the temperature and pressure have
ranges, retain the higher temperature and lower pres-
sure. Therefore, the actual maximum flow rate is:
Therefore, the nominal diameter is 40 mm. For obtain-
ing the minimum flow rate, retain the lower tempera-
ture and higher pressure.
From Tables C and D, the minimum flow rate at nominal
diameter of 40 mm and pressure of 0.95 MPa is 9 m
or, at pressure of 1.7 MPa, is 8 m
