How can we calculate airflow requirement (CFM) from a known heat load?
The airflow requirement depends on the acceptable temperature rise as air traverses through the computer unit. For air inlet temperature of 55 deg. F and a temperature rise of 20 deg. F, the required cooling airflow rate (CFM) can be calculated as: CFM = 154 x heat load (kW) This expression is valid at sea level and must be modified for higher altitudes.
