# How do you calculate the number to enter?

I know how to change the number in the Vetta Innovator C-100 cycle computer but I don't know how to calculate the number to enter. My tire size is 26'' by 1.9''.

The problem: "A piston cylinder device contains only saturated water vapor at 400 F. The piston is frictionless and sealed such that no mass crosses the boundary. the vapor is condensed at a constant temperature to saturated liquid." a)calculate the heat transfer and boundary work done during the process. b)if the cooling process then continues isobarically from point 2 until the liquid is further cooled to 100 F. Calculate the additional work done and additional heat transferred. ...point 2 being the saturated liquid state. I am having trouble finding an equation to use that does not incorporate volume or pressure. I need a guild into the right direction. Thank you.

Vetta uses circumference so yours would be 2055.

### Need instructions for 12 function cycle computer SW500NM

The number the computer gives you in the initial reset is a 4 digit number (the one mine gave me was 2124) with the last digit flashing. Since I had a 26" tire, I had no clue what I was supposed to enter. I eventually googled a page that gave me the answer. The actual size of my tire is 26x1.90. Go to: http://sheldonbrown.com/cyclecomputer-calibration.html#ccc

According to this page, our Schwinn 12 function computer falls in column "F" and the 4 digit number I would use to replace the 2124 number computer initially gave me (with the "4" flashing) would be 2055. This number represents my bikes actual tire size in the corresponding column. I had tried 2045, since it was the closest number the chart in the owner's book gave, but the speeds and distance computed didn't seem like it reflected much accuracy.

However, doing the math by comparison of 26x1.75 and 26x2 sizes, I find the 2055 number to be exactly the right number for my size tire (26x1.90) as listed in group F. I guess if you have a metric sewing measuring tape, you could measure the circumference of your tire and come close to the desired number, since that is what it is supposed to represent.

Since the manual that came with the computer can be confusing, I recommend going to that page if your tire size is not represented in the chart Schwinn provided with the computer. There is also a lot of useful information about bicycle tires in the other pages of the link I provided, too. Good luck.
