Q$5$: In a particular are welding process, the power source machine generates $4000$ W $.$ The metal to be welded is low$-$carbon steel, which has a melting point temperature of $1760$ Kelvin. Given that the cross$-$section area of the contentious fillet weld is $15m{m}^2,$ the heat transfer factor is $0\mathrm{.}8,$ and the melting factor is $0\mathrm{.}5.$ Determine the

$(6$ Points$)$ following:

A$)$ The rate of the heat energy received by the workpiece.

B$)$ The rate of heat energy losses due to the conduction process.

C$)$ The travel speed at which the welding operation can be accomplished in $m\frac{m}{s}.q,$
