That's extremely high pressure on the low side. While I believe there's still a good chance that you have an AC problem, I'm more inclined to believe that you have a faulty manifold gauge set than I am to believe your compressor isn't putting any pressure to the high side, and the low side pressure gauge may be faulty, as well. Tools are something where you get what you pay for - if you bought your gauge set at a place like Harbor Freight or Wal Mart, don't be surprised if it's faulty.
for smooth running pressure guage needle otherwise we can't get perfect mesurement
Eeeew, No! If anything, it would coat the needle with any oil naturally present in your hair.
Pressure is inversely related to the area on which force is applied. As the needle has pointed edge the pressure would increase and so it would be easier to go through the cloth for sewing purpose
There is the blood pressure cuff which wraps around the arm and the pressure guage I believe is called a "sphygmomanometer"
Because of the small area of the needle and the force that is exerted on the balloon. The pressure inside the balloon that was previously more, finally can diffuse into the room. Since the air canot all escape from the needle prick it bursts to equal the pressure.
80-110psi

if you don't have an 'eye' for evenness, take a ruler and draw a line with a removable ink pen. thread your needle and know the end. poke the needle up on the line and then down again a distance down the line you made. repeat for the length of the line. it will look like... _ _ _ _ _ _ _ _ _ _
you get a hematoma
AnswerWhat do you mean by haywire? Without more information, all I can tell you to do right now is to replace the filter you are using with an AC/Delco filter. The oil pressure sending unit may be defective if you are getting erratic readings. I mean that the water temp gauge needle goes way past the point to where it bottoms out and so does the battery volt gauge needle and the oil pressure gauge needle and the tach needle works when it wants to.
This pressure is always measured immediately upon insertion of the LP needle.
The pressure generated by a syringe is a result of how hard the plunger is pushed and the internal diameter of the needle, not the size of the syringe.
