$7\mathrm{.}5$ A$2)$ An industrial hydraulic system utilizes a $13\mathrm{.}7$ m long $12-$inch sch $80$ "steel" pipe to transport hydraulic fluid. If the pipe is full when the system temperature is $\backslash (20^\{\backslash$circ$\}\backslash$mathrm$\{$C$\}\backslash ),$ determine the required volume allowance $[$L$]$ for oil overflow when the system temperature rises by $\backslash (27^\{\backslash$circ$\}\backslash$mathrm$\{$C$\}\backslash ).$ You may assume that the hydraulic fluid may be approximated as "Engine oil $($unused$)",$ and that the pipe is free to expand$/$contract based on temperature changes.
