Calculating Drag

From $1

    I found some interesting information on how to calculate drag without a wind tunnel. This looks like a really good measure and will calculate every bit of drag including rolling resistance.

    Basically you measure how fast your scooter will slow down to 95 Km/hr when you pull the clutch in at 105Km/hr. Without brakes, the only thing slowing you down is drag, so knowing how fast you slow down tells you how much drag you have.

    I'll do the sums, give it a go and then write a simplified lab page on how to test.

    How can I measure the drag on a car?

    yep - I hope to write a little GPS phone application that does this automatically. That way I can test out the effect of different sitting positions and screens easily.
