Internal volume, fill hose?

Jump to latest Follow Reply
Unscrew hose from your gauge assembly unscrew remove the female foster quick disconnect.

Go to the faucet fill it with water then as it's coming out of the other end you plug it with your finger then plug the one close to the faucet with another finger then empty it onto a measuring cup measured in mililiters it's simplest since 1 mililiters equals 1cc.

Better idea grab 2 cups and one filled to the top with water and one empty. Siphon the water like you stealing someone's gas from their car's gas tank. Once it starts to flow plug that end with one finger then carefully plug the other end with another finger while still submerged in the full cup. Transfer to measuring cup in mililiters. One mililiter equals one cubic centimeter.

Here's your volume formula or go online. Intermediate school Chemistry...

Confused! here's your proof...

Can't go by weight though it's gonna be a tiny bit off.

I don't know any other real world way to measure your internal hose volume unless you have access to a lab.

The hose in your link is a microbore type so the answer to your question is not very much. Without knowing the exact ID of the said hose, it's impossible to estimate its volume with any accuracy. Filling it with water and measuring the contents will give you an accurate non-pressurized figure but will not allow for any expansion of the hose under pressure. If you just want to know how much air you're wasting when you bleed it the best answer is not very much.

ok 2 cc is the volume at a no pressure but how much air at 200 bar to fill 2cc volume, we still don't know how you are using this information, what is the problem you are solving by knowing the hose volume, if we may ask
Click to expand...

My calculations using .080 inches as bore size and 600 mm length are almost identical to aigun14's at 1.945 CCs or .1186912 CIs. At 200 BAR that grows to 389 CCs or 23.73824 cubic inches. I guess that you could ad 10-20% to those figures to allow for bore size dilation under pressure. Calculating pressurized volume is as simple as multiplying the swept volume by the pressure in BAR. This is another example of the simplicity of the metric system.
