Nitrogen is fed from a high-pressure cylinder through $1 \frac{1}{4}$ ID stainless steel tubing, to an experimental unit. The line ruptures at a point that is $10 \mathrm{ft}$ from the cylinder. If the pressure of the nitrogen in the cylinder is $3000 \mathrm{psig}$ and the temperature is $70^{\circ} \mathrm{F}$, what are the mass flow rate of the gas through the line and the pressure in the tubing at the point of the break?
