Water flows through $3/8$ in diameter boiler tubes. Before being heated, the water in

the pipe has a density of $62\mathrm{.}5$ lbm$/$ft$3$ and velocity of $10$ft$/$s$.$ What would the velocity

of the water to be downstream after it has been heated such that the water density is

$61\mathrm{.}8$ lbm$/$ft$3?$
