Thanks for clearing this up for me, but I am still confused on what exactly causes the low pressure region. You say that turbulent flow "doesn't really have anything to do with slipstreaming", while I read that it is the reason for it:
(from wikipedia)
A slipstream created by turbulent flow...
I agree with your reasoning as well. I also had thought of the lack of implications/continuity for an experiment focusing just on spheres, since if we look at more complex objects, the relationship that was determined would mean nothing; I previously believed that it might become a worthwhile...
I understand this completely and wasn't expecting an equation involving that many factors in anyway. It would be impossible to create a sensible formula that related so many variables.
I was wondering if any tests had been done in a specific environment where some factors are treated as...
Hey fellow Canadian
You should be fine if you find a thin enough electric cable. The one that connects your fluorescent lights to an outside socket should exit the fridge without hindering too much the seal of your fridge door. Other than unexpected spills of milk on the lamp :wink:, I don't...
Thanks for the response; however, I think I have found the answer to my initial inquiry in words:
I'm quite sure that decreasing the distance between two trailing objects, whatever shape or size such objects might be, will reduce the force of drag acting on the drafting object (the one at the...
I have been searching all over the internet for information on the physics behind slipstreaming or drafting, such as estimating the optimal distance an object should be behind another in order to experience the least drag. All I have found are a couple of Wikipedia articles as well as short...
Thanks for the response. I think I'm going to ignore the air resistance since it is relatively insignificant in the total resistance experienced by a moving object in water.
Oh and sorry for the confusion with the pennies. The pennies I am referring to are found in the bucket under the pulley...
For a physics experiment, I'm testing the drag experienced by floating models with shape, wetted surface, and velocity as the independent variables.
I placed the models in a flume tank and connected them to a hanging bucket via a string that passed over a frictionless pulley (see attached...
