Thanks for the response It is for a university project. the rubber is a RC car tyre and the cloth is from a belt sander. I don't think the layout you suggested would work for this case, do you have any other ideas?

Does anyone know where I can get those values? Haven't been able to find them anywhere

So I'm not sure if it was clear... If the convective coefficient for 5m/s is 30. Do I use that for all faces of the channel, or just the front? (where the wind is coming from?

I am wondering if in a case where the air velocity comes from one face as shown in the picture. Can I assume the whole area going along the channel will be subject to the same convective coefficient? Thanks

Thanks, so is the distance angular velocity x time? Also, surely the force has to be subject to the coefficient of friction?..

Homework Statement I need to find out how much heat is generated by a brake. I know heat generated = friction The parameters that will affect it friction are Normal load (I can choose depending on outcome) Coefficient of friction (assumed 0.8 between carbon fiber and steel plate) Area of...

Thanks for your help...

Thanks, but i think it might be an over estimate as I won't be getting a top of the range rack and pinion. I was hoping to use the worst case scenario for my calculations

I need to find out the transmission loss in rack and pinion but I can't find any formulas or some general figures...

Homework Statement I'm designing a tyre test rig for a university project to measure camber, slip angle etc. An example of a test rig - http://www.ika.rwth-aachen.de/forschung/veroeffentlichung/1999/30.06.-02.07/im173g.gif Although my test rig will be for an RC car tyres, so not quite the...

I know about the power harvested as I have performed an experiment and done some analysis on matlab. What I want is rough power consumption of an average car. (obviously the consumption is different at different speeds) It is just for comparison purposes to represent the % of potential energy...

I don't need anything exact and I don't have a specific car. I'm just interested in approximates power/fuel consumption at speeds like 30,50 & 70 mph. I'm doing a study on energy harvesting in suspension system and want to find out the % savings such systems could have on the average user.

I need rough values for power consumption of an average sized car at different speeds. Does anyone know how to either calculate or where I could find such information? Thanks

How do u calculate the volume of an aircraft wing? Would it work if I calculate the area of tip and root chord then times it by the span? Thanks

Here is what i mean
