PLEASE : make the answer in pound force $($Ibf$)$

Example $3\mathrm{.}6$

There is a steady one$-$dimensional flow of air through a $12-$in$.-$diameter horizontal duct $($Figure E$3\mathrm{.}6).$ At a section where the velocity is $460f\frac{t}{sec},$ the pressure is $50$ psia and the temperature is $550R.$ At a downstream section the velocity is $880f\frac{t}{sec}$ and the pressure is $23\mathrm{.}9$ psia $.$ Determine the total wall shearing force between these sections. Assume the flow to be turbulent and hence one$-$dimensional.

$V_1=460f\frac{t}{sec,V_2}=880f\frac{t}{sec}$

$p_1=50a,p_2=23\mathrm{.}9a$

$T_1=550R,$
