For walls 0.050 inch and thicker, grain size 5 usually is acceptable; for wall size around 0.015 in., grain size 6 usually is acceptable. For even smaller wall sizes, around 0.005 in., a grain size of 7 or finer is required. In general, as the wall thickness gets lighter, the need for a finer grain size increases.

The U-tube manometer - Dublin Institute of Technology

The U-tube manometer is shown opposite. The difference in the height of the two columns is due to the fact that p1 is greater than p2. For equilibrium at the datum point at the bottom of the tube the total pressure in each limb must be equal. The pressure in the left limb is due to (a) the column of measuring fluid (e.g. mercury) of height h 1 (b) the column of measurand fluid (e.g. …

Choosing the Right Centerline Radius Tube and Pipe Bending ...

Here are the selection and specs for 1-1/4" OD Round Tube Dies. To figure out the inside radius and outside radius, subtract and add half the outside diameter to the centerline radius. Note: These values will change slightly when you take the tubing out of the die and it springs back, but these values are close enough for selecting your die.

Mil Spec Buffer Tube vs Commercial Buffer Tube

How can I tell which size I need? As we mentioned above – you need to match the stock to the buffer tube. Most stocks come in both mil-spec and commercial varieties. The best way to measure is by using a micrometer, and measuring the diameter of the tube. A mil-spec tube should measure about 1.146", and a commercial will be about 1.17".
