What is the gauge pressure in the syringe

Reference no: EM13341153

1. A hypodermic syringe has a piston area of 0.5 cm^2 and a needle with circular opening of diameter 0.2 mm. What is the gauge pressure in the syringe while pushing the piston with 1 N of force? (Answer in mm Hg).

2. Suppose a lower gauge pressure of 60 mm Hg exists inside the body where you are injecting the hypodermic fluid. What is the net force on the fluid as it exits the needle? (Answer in Newtons).
