I am a doctor with limited mathematics knowledge. I am trying to prove to my medical fraternity that for a given force of aspiration, a smaller syringe generates a higher "negative pressure". I did a small experiment. I hung an one kilogram weight on a 5 ml and 10 ml syringe and connected it to...
"reverse pitot"
if one reverses the direction of flow in a pitot measuring system (i.e the pitot tube doesn't face the flow), will there still be a difference in pressure between the pitot and static tube ?
I am a medical doctor needing some physics help. Quite often in patients we insert thin tubes into blood vessels for various purposes. These occasionally get blocked and we use syringes to try and clear these blockages. We attach a syringe and create a "negative pressure" by drawing back the...
