Is their any way to calculate the actual flow rate through the FCU when the design & Actual Parameters are as....

System Installed with Auto Flow Valve with a catridge for 0.23L/sec requires a minimun differential pressure of 19 Kpa for the specified flow rate as recommended by Manufacturer.

Design Flow Rate: 0.23 L/s
Measured Diff. Press. across Auto Flow Valve: 79Kpa
Coil Pressure drop (frm Manufacturer): 8.28 Kpa
Measured Pressure Drop at Coil: 13.20 Kpa

Please advise how to calculate actual flow rate through the coil?

Thanks for helps.
