$($Fanno flow$)$ A long, smooth wall pipe $(f=0\mathrm{.}01)$ is to deliver $11500f\frac{t^3}{m}in$ of air at $60F$ and $14\mathrm{.}7$ psia $.$ The inside diameter of the pipe

is $0\mathrm{.}6$ ft and the legth of the pipe is $120$ ft $.$ Determine $($a$)$ the static tempeature and $($b$)$ the pressure required at the pipe entrance if the

flow through the pipe is adiabatic.
