    Rainwater Defense by Test Speed

    High Rain Defense Candidates

    Formula basis: face velocity = airflow / gross area; effective velocity = airflow / (gross area * coefficient); pressure drop = 0.5 * air density * effective velocity squared. Rainwater defense sequence is listed for 0.0, 0.5, 1.0, 1.5, 2.0, 2.5, 3.0, and 3.5 m/s test velocities. Values are for preliminary aerodynamic review and should be checked against manufacturer data and project requirements.
