1 the hypodermic needle shown below contains a liquid serum, Ask an Expert

Engineering

1. The hypodermic needle shown below contains a liquid serum (ρ = 1 g/cm³). If the serum is to be injected steadily at 6 cm³ /s, how fast should the plunger be advanced (a) if leakage in the plunger clearance is neglected and (b) if leakage is 10% of the needle flow?

2. Incompressible steady flow in the inlet between parallel plates is uniform, V₀ = 8 cm/s, while downstream, the flow develops into the parabolic profile v_x= az(z_{0 -} z), where a is a constant. What is the maximum value of v_x?
