how much difference does an inch of diameter make?

You can put the thin smooth tires on your mountain bike.  Almost all tire manufactures make some type of slick for all mountain bikes.  It's a lot cheaper than buying another bike just because you like the tires.\n\nAnd don't let the thick rims fool you.  Clenchers are clenchers and you can put just about any width tire on them.\n\nI pasted two links below of slick mountain bike tires from Performance.  Like I said, any bike shop will have 'em or they can get 'em for you.  Or you can just order online.\n\nI've had the ritchey's before.  Lot's of tread and they last a long time for the money.  \n\nGood luck!\n\nHappy tire swapping!

Imagine cutting the tube down its length and opening it up into a long, narrow rectangle.  The outside area would be the length times the width.  The width of the rectangle is really the circumference of the circular cross section of the tube.  Thus, since you know the diameter, you have this:\n\nsurface area = length * pi * diameter\n\nwhere pi is approximately 3.14159265358979.\n\nNote, if the tube is not flexible, you have to be careful measuring the length of the bent tube.  it is the length of an imaginary line through the center of the tube, but as the other answerer pointed out, you can get this by taking the average of the "inside the curve" length and the "outside the curve" length.  Of course, if the tube is flexible, just straighten it out and measure it.\n\n\nNote--straightening, cutting and opening up, etc., will change the area slightly as it stretches part of the tube and compresses another part--this is a very small effect (unless you tie the tube into a tight knot or something) and probably can't easily be measured well anyway--should be too small to matter in most applications.

I may get confused on this. Increasing diameter lowers the pressure, but, increases volume. In a house we normally use a large pipe as a main and it supplies volume. Then we decrease pipe size to various Faucets and Water Heaters depending on their input size. When done properly you can flush a toilet without the shower burning someone. A sink Faucet will have more pressure from less diameter, but, it will have less volume. So, a sink faucet may fill a gallon jug slower than the Garden Hose Faucet. I hope I explained this correct. Been a while I worked with this stuff.\nYea, what is said above more correct, I give them a Thumbs Up. Velocity what I was trying to think of. Like a spray nozzle on a Garden Hose. The velocity make it seem it more pressure.

A diameter can be any number.\nNot just any real number... any finite cardinal number.  So you need to give us more information here.

The New Zealand inches are upside down relative to the U.S.A. inches. :-)\n\nIf you define one inch so that one meter is exactly 39.37 inches then you get one length.  If you define one inch as exactly 2.54 centimeters then you get a very slightly different length (do the math).  Both of the above refer to the international standard for the meter, of course.  If there is a difference between the two (besides the upside down thing) then it is probably in which of the above definitions they adopt.

No. They do not share the same dimensions.\n\nYou can multiply them though.

Diameter will be 1 units\n\nCircumference =piD\nif Circumference =pi\nthen D=1

What difference would it make!!!

I am not sure of the exact size, but my guess is that it has a diameter of about 1/2 of an inch.

It would probably help if you posted the definitions.\n\nIn general, though the "scale factor" is usually the the ratio of the size of a copy of an object to the actual size of the object.\n\nAs an example, if you look at a map, they usually say somewhere something like "1 inch = 10 miles".  So if you are trying to find the distance between two cities, and they are 3.5 inches apart on the map, the cities are 3.5 inches x 10 miles/inch = 35 miles apart.\n\nSince the scale factor IS a ratio, I don't understand the second question.

there is 0.0254 in one inch.

Diameter goes from one side of a circle through the center to the other side.  Radius only goes from the center to one side.

there are about 2.54 centimeters in an inch. No one is sure about the exact measurement

the radius is 1/2 the distance across a circle, while the diameter is twice the radius and is a straight line passing through the center of the circle to another side of the circle.
