Nnstatic pressure calculation pdf merger

External static pressure is basically and simply the pressure required by a fan which is located inside any hvac equipment to deliver the required design airflow rate and to allow air to reach from the hvac equipment to the index point so air can be discharged with the required airflow rate even from the furthest air outlet diffuser or air.
