•A uniform steady water flow of 1m/s occurs in a 25MM diameter pipe. Taking viscosity of water as 1014 x10-3 Ns/m2 determine Reynolds number and hence decide if the flow is turbulent or stream line.
What's the answer please chaps?

Surely you know the foumla for Re?
Re=(density*velocity*length)/viscosity
Re=(1000*1*25*10^-3)/1014*10^-3
Re=24.655 (3dp)
I think you've got yourself a laminar flow.

Using the standard Re Number calculation the flow will be laminar.

you have
Re=(length*velocity*density
)/viscosity
So Re=(1*1*1000*0.025)/1014x10-3=24.65483
as it reflects laminar flow
