Water at an average bulk temperature of $80$F flows inside a horizontal smooth tube

with wall temperature maintained at $180$F$.$ The tube length is $2$ m$,$ and diameter is

$3$ mm$.$ The flow velocity is $0\mathrm{.}04$ m$/$s$.$ Calculate the heat$-$transfer rateWater at an average bulk temperature of $80F$ flows inside a horizontal smooth tube
