Determining Pressure drop in cap tubes?

[Raadster]

Are there any charts or sources of information which outline the pressure drop occuring along a certain length of captube.E.g. Pressure drop in 1m of 0.031 inch captube as opposed to 1m in 0.026 inches.

A search on the Forum will bring up lots of discussion on Cap Tubes etc

See if this Danfoss program will help you.

There is all so a current great thread on the fluid dynamix of a cap tube!

Impossible to put those in charts: refrigerant, liquid quality, SC, sort and quality of capillary, DP over capillary... are determining factors.
