hey guys
As the title suggests i need a little help with my results from my thermofluids lab, i am trying to come to a conclusion about two of my graphs which are attached.
The lab is looking at measuring the drag forces involved with a model car using pitot tubes to measure the pressure drops.
my understanding is that because Fd(total drag force) is proportional to V^2 then the drag coefficient is not affected due to the equation cd= Fd/ 1/2 ρ v^2 A . as the fd and v^2 cancel each other out? am i correct in this ? am i right in say " the graph shows that an increase in the velocity does not affect the drag coefficient" ? and the same with Reynolds number?
If i am completely wrong let me know
