Air Flow Pressure Drop Through Coils

[donkeer]

I am new to the HVAC world and I am working with condensate coils. I have searched to find a rough calculation of projected pressure drop as air passes through a condensor coil but have found nothing. Is there a quick calculation that allows air flow, coil size, # of coil passes, fins per inch, etc. that will get me to +/- 15% of delta P?

Hi,
There are many coil selection program from various vendors. You could use them just to find your air DP, and ignore other information that the coil program prints out.
