Three Key Words in Hydraulic Hose Sizing: I.D., Dash Size

17/8/2017· Simply put, a dash size refers to an I.D. of a hydraulic hose or fitting in 1/16" increments. For example, -6 hose would indie a hose with I.D. of 6/16" - or 3/8". Hoses are measured by inside diameter, unlike tubes which are measured by outside diameter. As a matter of fact, that is how the hoses and tubes are differentiated.

Practical Considerations in Pump Suction Arrangements

to the nominal pipe diameter (D). In the long radius elbow, A is equal to 1.5D. Obviously, the long radius 90Eelbow is more “sweeping” and imparts less tur-bulence and unbalanced flow than that of the short radius; it should be used whenever suction elbows are unavoidable.

Crankcase Vacuum Facts - Racing Engines & High Performance

First of all, in most engines, the expected power gains will occur with 8 to 10 inches HG crankcase vacuum. Beyond that point, more vacuum does not generally produce any measurable power gain until (a) you get more than 20 inches HG of vacuum AND (b) you are operating in excess of approximately 8300 RPM. However, we generally size the systems

Vacuum and Hose Performance - Kongsberg PTFE Hose

The primary factors that affect hose performance under vacuum are hose size and construction, temperature and bend radius. Hose construction determines the ‘hoop’ strength or the relative ability of the hose to resist collapse. Generally, smaller IDs, thicker walls, external reinforcement such as wire wrap or covers and bonding together the hose layers serve to increase hoop strength. As the temperature of …

Does vacuum hose size matter?

17/5/2020· Also, does hose diameter affect vacuum? Smaller diameter vacuum hoses are often more maneuverable and flexible, not to mention lighter, and for certain appliions there are performance benefits. Larger diameter hoses can pick up bigger debris, and with less likelihood of clogging. The diameter is doubled, and so the cross sectional area is quadrupled.

Understanding Vacuum and Vacuum Measurement

High Vacuum – is vacuum where the MFP of residual gasses is longer than the size of the chaer or of the object under test. High vacuum usually requires multi-stage pumping and ion gauge measurement. NASA has revealed that the vacuum level recorded on the moon was 1x10-9 Torr. 1 Ultra-High vacuum – requires baking the chaer to
