QUESTION $2(10$ MARKS$)$

The following expression of water flowing over a horizontal plate is true:

$=0\mathrm{.}628P^{0\mathrm{.}5}(0\mathrm{.}954+Pr{)}^{-0\mathrm{.}24}.G{r}^{0\mathrm{.}25}$

The water is at a temperature of $60C$ and the outside surface temperature

of the plate is $425C.$ Calculate the heatloss by convection if the plate's

dimension is $2\mathrm{.}3m700mm$ and $3$ cm thick.
