Q$19.$

$($i$)$ Wind at $\backslash (50\backslash$mathrm$\{$~km$\}\backslash$cdot $\backslash$mathrm$\{$hr$\}^\{-1\}\backslash )$ is blowing lengthways and parallel to the wall of a house of length $10$ m and height $3$ m $.$ If the surface temperature of the wall is $\backslash (10^\{\backslash$circ$\}\backslash$mathrm$\{$C$\}\backslash )$ and the surrounding air is $\backslash (0^\{\backslash$circ$\}\backslash$mathrm$\{$C$\}\backslash ),$ determine the rate of convection heat transfer from the wall to the surroundings. $(7$ marks$).(9599$ W$)$

$($ii$)$ If a laminar flow regime only was to occur over the entire house wall, what would be the maximum permissible Reynolds Number? Explain. $(3$ marks$).$
