Answer (Detailed Solution Below)
Detailed Solution
Download Solution PDFExplanation:
For a laminar fully developed flow through pipes, the friction factor, f is found from the exact solution of the Navier-Stokes equation is given by:
\(f = \frac{{64}}{{Re}}\)
\(f \propto \frac{{1}}{{Re}}\)
Where , f = Friction factor, Re = Reynolds Number
Thus, the friction factor is inversely proportional to Reynolds Number. So, after plotting in the log plain it is like a straight line coming downwards. So, that is what you see for the laminar flow in the moody chart.
