$)$ Air at $25$degrees flows past a flat plate $2\mathrm{.}5$m$/$s$.$ the plate measures $600$mm x $300$mm and is maintained at a unit temperature of $95$ degrees. Calculate $($a$)$ the heat loss from the plate if the air flows parallel to the $600$mm side. $($b$)$ how would the heat lost be affected if the flow of air is made parallel to the $300$mm side
