Required information

Consider a $12-m-$high and $2-m-$wide glass window with a thickness of $6$ mm $,$ thermal conductivity $k=0\mathrm{.}78\frac{W}{m}.K,$ and emissivity $=0\mathrm{.}9.$ The room and the walls that face the window are maintained at $25C,$ and the average temperature of the inner surface of the window is measured to be $5C$ and the temperature of the outdoors is$.C.$

Given: The properties of air at $T_{f,C}=15C.$

$k=0\mathrm{.}02476\frac{W}{m}*C$

$y=1\mathrm{.}470{10}^{-5}\frac{m^2}{s}$

$Pr=0\mathrm{.}7323$

Determine the convection heat transfer coefficient on the inner surface of the window.
