Gaseous chlorine $(\mathrm{M}=71)$ is transferred from a high-pressure storage tank at 500 psia and $60^{\circ} \mathrm{F}$, through an insulated $2 \mathrm{in}$. sch 40 pipe $200 \mathrm{ft}$ long, into another vessel where the pressure is 200 psia. What is the mass flow rate of the gas and its temperature at the point where it leaves the pipe?
