Question

How its solved

Answer 1

Answer #1

cross sectional area = 0.8 mm² = 0.8*10^-6 m²

average velocity = rate of flow / cross sectional area

= 5*10^-6 /0.8*10^-6

= 6.3 m/s

A patient in the hospital is receiving a saline solution through a needle in their arm. The needle is 2.20 cm long, horizontal, with one end in a vein in the arm, and the other end attached to a wide tube that extends down from the bag of solution, which hangs from a pole so that the fluid level is 90.0 cm above the needle. The inner radius of the needle is 0.250 mm. The top of the fluid is...
