Let's consider a flat concrete wall of width $$w$$ = 0.10 m
and surface area $$S$$ = 20.00 m<sup>2</sup>.
The surfaces at $$x$$ = 0 and at $$x = w$$ are maintained at temperatures
$$\theta_0$$ = 0.0 °C and
$$\theta_w$$ = 20.0 °C.
It will be assumed that the heat transfer is in one direction and in steady
state, without internal sources and that the thermal conductivity of medium
concrete is
$$\lambda$$ = 0.50 W/m·K.

**Give the values of:**

$$U$$ = {1:NUMERICAL:=5.00:0.5} (±0.5) W/m<sup>2</sup>K,
thermal transmittance

$$R$$ = {1:NUMERICAL:=0.010000:0.005} (±0.005) K/W,
(absolute) thermal resistance,

$$\varphi_{0,w}$$ = {1:NUMERICAL:=-100.00:10} (±10) W/m<sup>2</sup>,
heat flux from $$x$$ = 0 to $$x = w$$,

$$q_{0,w}$$ = {1:NUMERICAL:=-2000.00:100} (±100) W,
heat transfer rate from $$x$$ = 0 to $$x = w$$.
