A compressor supplies natural gas (mainly $\mathrm{CH}_{4}$ ) to a pipeline. The compressor suction pressure is 20 psig and the discharge pressure is $1000 \mathrm{psig}$. The pipe is $5 \mathrm{in}$. sch 40 and the ambient temperature is $80^{\circ} \mathrm{F}$.

(a) If the pipe breaks at a point 2 miles downstream from the compressor station, determine the rate at which the gas will escape (in scfm).

(b) If the compressor efficiency is $80 %$, what power is required to drive it?
