Using this flow sheet to illustrate a few points discussed earlier......
To convert from the 3” pressure used for that test, to 10”...... you use a C/F of .547.
That chart shows 108@3”, which corrects to 194.7@10”.
The valve is 2.19” diameter.
At .100 lift the area is .688sq/in.
At 86.7cfm per sq/in, and 100% C/D the flow would be 59.6cfm@10”.
The chart shows [email protected] lift, at 3” test pressure.
22/.547 = 40.2cfm
40.2/59.6 = C/D of .674
