Flow Rate through Fan Coil Unit
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.

Re: Flow Rate through Fan Coil Unit
If your auto-valve is working then your flow rate is 0.23l/s.
The fpressures at the coil would indicate a higher flow rate but are the pressure test points the manufacturers test points or your own?Brian - Newton Abbot, Devon, UK

Get an annometer and check for yourself the actual air flow.
