Hello, I have a question about airflow through a car radiator which has a plate on the discharge side with holes cut for fans. There are fans mounted on there but they aren't being used. And the car is moving. Would the airflow increase or decrease with the plate on there? We are having a discussion about this and I am fairly sure that it would decrease as it is a restriction on the airflow. Others have been saying it would increase as there is a slight vacuum created on the discharge side creating more flow. None of us have any real physics teaching, just your average high school stuff. Sorry if it is a silly question. Thanks in advance. Edit: Also I haven't read through the forum rules here, I hope I haven't broken any, please let me know if I have. Thanks again.
