How long should a laminar flow hood run before it can be used?
Laminar flow hoods and hepa filter must be certified every 6 months. The type of environment that a laminar flow hood provide ISO 5, which is formerly known as a Class 100 area.
Should electric field lines be smooth curves?
There is no "should". The question is not a matter of ethics, morality, or civilized culture. But there's no doubt that they are. If you need a reason, a great one is the requirement that they be continuously differentiable.

I think you would have to ask an operating company this, I don't have any real world figures. I should find your nearest operating plant and the name of the owners and ask them.

What are examples of laminar and turbulent flow?
The Reynolds number, Re = VD/υ, can be used to measure the laminarity of flow. The smaller the Reynolds number, the more laminar the flow. Therefore, to achieve better laminar flow, V and D (velocity of fluid and diameter of pipe) should be small and υ, the kinematic viscosity of the fluid, should be large. Therefore, since pipe diameter and viscosity is fixed in this circumstance, the slower the velocity of the flow, the more laminar the flow. Open the faucet to a small degree and the flow will be laminar. Turn the facet open fully will (for some faucets) cause turbulent flow depending on the maximum velocity of water allowed by the faucet.
