Flow Velocity- Guranteed to be Laminar

AI Thread Summary
To determine the maximum average flow velocity of water in a pipe while ensuring laminar flow, one must calculate the Reynolds number using the provided constants. The critical Reynolds number for laminar flow is typically 2000, and the formula for flow velocity can be derived from the relationship between flow rate, viscosity, and pipe diameter. Participants suggest posting the question in a dedicated homework section for more targeted assistance. Understanding the principles of fluid dynamics and the relevant equations is essential for solving this problem. Accurate calculations will yield the desired flow velocity in mm/s.

I am absolutely stumped on this last question for my assignment, I have no idea what to or how to calculate the flow from just these given constants.

Q) Water (p = 998 kg/m^3
, n = 1.0*10^-3 Pa.s at 20C) at 20C flows through a pipe of
diameter 50.0 mm. What is the maximum average flow velocity if the flow is
guaranteed to be laminar? Give your answer in mm/s.

You have to decide a limiting Reynolds number for laminar flow and apply the formula that relates to a tube. If you've had a course this question must be pretty close to it.
 
O thanks I will post in the homework section.
 
The rope is tied into the person (the load of 200 pounds) and the rope goes up from the person to a fixed pulley and back down to his hands. He hauls the rope to suspend himself in the air. What is the mechanical advantage of the system? The person will indeed only have to lift half of his body weight (roughly 100 pounds) because he now lessened the load by that same amount. This APPEARS to be a 2:1 because he can hold himself with half the force, but my question is: is that mechanical...
Some physics textbook writer told me that Newton's first law applies only on bodies that feel no interactions at all. He said that if a body is on rest or moves in constant velocity, there is no external force acting on it. But I have heard another form of the law that says the net force acting on a body must be zero. This means there is interactions involved after all. So which one is correct?
Thread 'Beam on an inclined plane'
Hello! I have a question regarding a beam on an inclined plane. I was considering a beam resting on two supports attached to an inclined plane. I was almost sure that the lower support must be more loaded. My imagination about this problem is shown in the picture below. Here is how I wrote the condition of equilibrium forces: $$ \begin{cases} F_{g\parallel}=F_{t1}+F_{t2}, \\ F_{g\perp}=F_{r1}+F_{r2} \end{cases}. $$ On the other hand...
