Has anyone had similar experiences? This means the flow speed is 0 at the edges and smootly peaks in the middle. The vein may collapse as a result of this. The average still needs to be what was calculated above, but the power will be higher because it scales with the square of the speed. Anyway - love the I'ble. If the plunger is sticking, you can try lubricating it with water or saline. For a 1 cm^2 piston, that would give a force of 76 N (if I did the math correctly). $P_2$ = pressure at the exit of the needle (atmospheric) $\gamma = $ density times gravitational acceleration $=pg$, $v_1 =$ the speed of the plunger is pretty much negligible when compared to the speed of the fluid expelled through the needle, $h_f =$ all the frictions due to diameter reduction etc. Hence, the minimum force will be calculated as follows: Force = Area of plunger 1 2 p V 2 2.

I know ink cant just be injected lol. Depress the plunger and push the air into the vial. Align the flat surface of the black rubber plunger with the 10 unit line. The plunger should be completely depressed before the needle is inserted into the skin. Open the syringe latch by swinging it in a counterclockwise direction. If you use a syringe barrel of 10 ml or larger, make sure not to pull the plunger too quickly. Intro text on building a small fluid pressure chamber? At 0.5 cc/sec, for 18 gauge, the shear rate at the wall will be 8600 sec^-1, and the shear stress at the wall will be 80000 dynes/cm^2. If the black piece connecting the plunger to the barrel broke off and became stuck (a sign that you have been using that tool in an improper manner for far too long).
