Cooling tower capacity @ fan failure
Cooling tower capacity @ fan failure
(OP)
I would like to know which is the residual cooling capacity of a counter flow cooling tower with high efficiency packing working 100% if the fan fails. a rough estimate (+/- 20%) is enough.
Kind regards

RE: Cooling tower capacity @ fan failure
With the calculated stack effect, you can subtract the air pressure drop for tower fill. There will be a pressure difference and it will be small.
Leaving air will be saturated if the pump doesn't fail, too. There will be a latent and dry-bulb component to the capacity.

The stack effect would not be enough to overcome the resistance to airflow through the fills.The manufacturer can give you figures for air pressure drop at rated flow rates
