All,
Can any one explain the meaning of the following, I have came across the same in one of the Air Cooler Datasheet:
Exchanger to be designed 125% of flow and 120% of surface Area
Does it mean that the exchanger shall have 25% margin on the flowrate and 20% excess area on top of that.
For me 20% excess area for a Air Cooler is over the top requirement.
Thanks in advance.
Regards.
