Plot graph of friction factor vs reynolds number.

Plot graph of total head loss vs velocity.

Question

Identify laminar and turbulent flow regimes in your experiment. Give the range of calculate reynolds number.

Compare your results for $f$ with the Moody chart. Note that the pipe used in this experiment is a smooth pipe.

What natural processes would affect pipe roughness?

App$\mathrm{.}1-$ List of Formulae

The Fanning factor in laminar flow is:

$f_F=\frac{16}{Re}$

The Darcy factor in laminar flow is:

$f_D=\frac{64}{Re}$

Reynold number can be calculated:

$Re=\frac{VD}{}$

where:

$=$ Density of fluid, $k\frac{g}{m^3}$

$v=$ Velocity of fluid, $\frac{m}{s}$

D $=$ Pipe interior diameter, m

$=$ Fluid dynamic viscosity, $k\frac{g}{m}.s$

From volumetric flowrate, we can calculate the velocity:

$v=\frac{Q}{A}$

$A=\frac{D^2}{?}$
