$($Show work and steps. Circle$/$box final answers$)$ Problem $2$

Air flows out of a pipe with a diameter of $0\mathrm{.}3$ m at a rate of $1000($m$^(3))/($m$)$in at a pressure and

temperature of $150$ kPa and $293$ K $,$ respectively. If the pipe is $50$ m long, assuming that $()/($bar$)($f$)=0\mathrm{.}003,$

calculate the Mach number at the exit, the inlet pressure, and the inlet temperature.
