Making the approximation for steady velocity riding that the water column will began to flow in unison over time yes it would be a straight...

### Has anybody ever inflated there bicycle tires with water and done a power study

I speak to my professors regularly about this. I've taken many lab courses and know how difficult it is to control a experiment and get worthwhile...

If you road a steady velocity because of friction the water would eventually approach the same rotational speed of the bike wheel. Accelerating...

The point is that by finishing where you started you eliminate the variable of work done on or by the gravitational field making the test a more...

### Has anybody ever inflated there bicycle tires with water and done a power study

Yeah I realize all of that. The point is that because gravity is a conservative field if you finish where you start you've done no work in the...
