A fluid, flowing in a $5-$cm$-$I.D$.$ pipe with an average velocity of $1\mathrm{.}83\frac{m}{s},$ is being heated. The heat transfer coefficient at the wall is $h=1,703\frac{W}{m^2*(K)}.$ Properties of the fluid are given:

$=0\mathrm{.}9cP$

$=801k\frac{g}{m^3}$

$c_p=3,348\frac{J}{kg*K}$

$k=17\frac{W}{m*K}$

The value of the Prandtl number Pr is most nearly:

A $0\mathrm{.}177$

B $5\mathrm{.}64$

C $100$

D $81,400$
