A wall in a house contains a single window. The window consists of a single pane of glass whose area is 0.11 m2 and whose thickn

Assoli18 [71]

Answer:

Explanation:

Given that,

The area of glass $A_g$ = $0.11m^2$

The thickness of the glass $t_g=4mm=4\times10^-^3m$

The area of the styrofoam $A_s=11m^2$

The thickness of the styrofoam $t_s=0.20m$

The thermal conductivity of the glass $k_g=0.80J(s.m.C^o)$

The thermal conductivity of the styrofoam $k_s=0.010J(s.m.C^o)$

Inside and outside temperature difference is ΔT

The heat loss due to conduction in the window is

$Q_g=\frac{k_gA_g\Delta T t}{t_g} \\\\=\frac{(0.8)(0.11)(\Delta T)t}{4.0\times 10^-^3}\\\\=(22\Delta Tt)j$

The heat loss due to conduction in the wall is

$Q_s=\frac{k_sA_s\Delta T t}{t_g} \\\\=\frac{(0.010)(11)(\Delta T)t}{0.20}\\\\=(0.55\Delta Tt)j$

The net heat loss of the wall and the window is

$Q=Q_g+Q_s\\\\=\frac{k_gA_g\Delta T t}{t_g}+\frac{k_sA_s\Delta T t}{t_g}\\\\=(22\Delta Tt)j +(0.55\Delta Tt)j \\\\=(22.55\Delta Tt)j$

The percentage of heat lost by the window is

$=\frac{Q_g}{Q}\times 100\\\\=\frac{22\Delta T t}{22.55\Delta T t}\times 100\\\\=97.6 \%$
