1/4" vs. 3/8" air hose, does it matter? - by Jim B

8/2/2021· As an example, I punched in the nuers for a 20 foot length of 1/4” hose at 90 PSI and 13CFM. For 1/4”, that comes back with a little more than 15psi loss (.78psi/ft), while a 3/8” hose has just a bit less than 2psi loss (.09psi/ft). At 50 feet, that 1/4” hose will have a drop of almost 40psi at the end, and a 3/8” hose would only

Understanding Compressors. Sliding Vane Compressors. A sliding-vane compressor relies on a series of vanes, mounted in a rotor, which sweep along the inside wall of an eccentric cavity. The vanes, as they rotate from the suction side to the discharge side of the eccentric cavity, reduce the volume of space they are sweeping past, compressing the gas trapped within the space.

Impeller Size - an overview | ScienceDirect Topics

Moving up a compressor frame size has an efficiency advantage. Compressor efficiency increases with impeller size - both due to Reynolds nuer effect and reduced relative surface roughness. For the relatively small, high-speed centrifugal compressors in the 200 to 700 kW th capacity range, peak efficiency increases about 2% for each jump in frame size.

Flow Rate Calculator - RapidAir Products

The thread size of the port on your air compressor tank does not determine the pipe size for your piping system. It is calculated with the length of your piping (building size) and air compressor CFM output. Even though the port on your tank may be small, the air is only traveling through a short distance, so the restriction is minimal.
