how to build wind tunnel . want to test how speed effect lift on different objects.
if you look on your first post https://www.sciencebuddies.org/mentorin ... c.php?t=82
this question was already answered. If you would like to ask another question, go ahead. However, please do not keep asking the same question in several new topics.
I realize this is a slightly different question (speed vs. weight), but I think you would get a better response by posting in only one topic. Also, the basic idea of the wind tunnel is the same regardless of what you are testing. With this change you need a variable fan.
