$6\mathrm{.}3($a$)$ The friction and minor losses are tabulated

in Example $6\mathrm{.}2.$ Draw the losses to scale, as in Fig.

$6\mathrm{.}4$ in Example $6\mathrm{.}1.($b$)$ Repeat Example $6\mathrm{.}2$ using

a $0\mathrm{.}6m$ diameter pipeline over the entire $2\mathrm{.}0km$

length between the reservoirs and recalculate all of

the losses. What proportion of the total head loss is

the result of friction in the $0\mathrm{.}6m$ pipeline?

$[0\mathrm{.}197m$; $52\mathrm{.}410m$;$0\mathrm{.}393$; about$\frac{99}{\%}]$
