Question: average velocity volume flow rate...

Question details

3) 140 points) Apply results from #2 to the following problem: Water at 293 K flows through the horizontal pipe diameter of 2cm with a pressure drop of 90 N/m3. a) Find the mass flow rate. b) Find the average velocity of the flow. c) Determine whether the flow is laminar or turbulent (hint: use Reynolds number). d) Find the diameter of the pipe for which one could expect a transition from laminar to turbulent flow at the same conditions (temperature and pressure drop).

average velocity:

volume flow rate:
