A room has a wall, and I'm trying to determine the heat loss from this room through this wall. My teacher set up these two equations for me;(adsbygoogle = window.adsbygoogle || []).push({});

[tex]

m \cdot C_P \cdot {{dT_m } \over {dt}} = U \cdot A\left( {T_R - T_m } \right)

[/tex]

and

[tex]

Q_P + \rho \cdot C_P \cdot \dot V\left( {T_R - T_{out} } \right) = U \cdot A\left( {T_R - T_{out} } \right)

[/tex]

I understand the first equaton to some extent, it will give me the wall temperature as a function of time once I solve it, but I don't really see what I'm to use the second one for...anyone?
