A flat plate measuring $2$m in length and $0\mathrm{.}8$m in width has a density of $3000$ kg$/$m$\text{'}$ and a specific heat of $700$ J$/$kgK$.$ Initially, the plate's temperature is $80\backslash$deg C$.$ Air at a temperature of $20\backslash$deg C$,$ flowing at a velocity of $2$ m$/$s$,$ is blown over both surfaces $($top and bottm$)$ of the plate along its width. Calculate the rate of heat dissipation from the plate.Use the correlation Nu $=0\mathrm{.}664\backslash$times Re $\mathrm{.}5$ xPr$0\mathrm{.}3333$Properties of the air at $50\backslash$deg C:Density $($p$)$: $1\mathrm{.}09$ kg$/$m$\text{'},$ Specific heat $($C$)$: $1\mathrm{.}007$ kJ$/$kgK$,$ Thermal conductivity $($k$)$: $0\mathrm{.}028$ W$/$mK$,$ Prandtl number $($Pr$)$: $0\mathrm{.}698,$ Dynamic viscosity$(4)$: $2\mathrm{.}03\backslash$times $10-$kg$/$ms
