Discussion Overview

The discussion revolves around a homework question related to fluid dynamics, specifically calculating the maximum average flow velocity of water in a pipe under laminar flow conditions, given certain physical constants.

Discussion Character

  • Homework-related

Main Points Raised

  • One participant expresses confusion about how to calculate the flow velocity from the provided constants.
  • Another participant suggests determining a limiting Reynolds number for laminar flow and applying the relevant formula for flow in a tube.
  • A participant indicates they will move the discussion to the homework section for further assistance.

Areas of Agreement / Disagreement

Participants do not reach a consensus, as the initial poster is unsure about the calculation, while another provides a suggestion without confirming its correctness.

Contextual Notes

The discussion lacks specific details on the Reynolds number value considered for laminar flow and does not provide the formula referenced for calculating flow velocity.

Who May Find This Useful

Students or individuals interested in fluid dynamics and homework assistance related to flow calculations in pipes.

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.

Homework question?

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.
