A gas storage cylinder contains nitrogen at 250 psig and 708F. Attached to the cylinder is a 3 in. long, 1/4 in. sch 40 stainless steel pipe nipple, and attached to that is a globe valve followed by a diaphragm valve. Attached to the diaphragm valve is a 1/4 in. (ID) copper tubing line. Determine the mass flow rate of nitrogen (in lbm/s) if

(a) The copper tubing breaks off at a distance of 30 ft downstream of the diaphragm valve.

(b) The pipe breaks off right at the cylinder.
