5. For laminar flow condition, what size of pipe will deliver 6 liter per second of oil having kinematic viscosity of 6.1x10^-6 m²/s?

6. A fluid at 0.001 m³/s through a 100-mm-diameter pipe. Determine whether the flow is laminar or turbulent if the fluid is (a) hydrogen (v=1.08x10^-4m²/s), (b) air (v=1.51x10^-5m²/s), (c) gasoline (v=4.06x10^-7m²/s), (d) water (v=1.02x10^-6m²/s), (e) mercury (v=1.15x10^-7m²/s), or glycerin (v=1.18x^-3m²/s)

7. Which fluid at room temperature requires a larger pump to flow at a specific velocity in a given pipe: water, gasoline, or glycerin? Why?
