$5\mathrm{.}101.$ A gas mixture consisting of $15\mathrm{.}0$ mole $\%$ methane, $60\mathrm{.}0\%$ ethylene, and $25\mathrm{.}0\%$ ethane is compressed to a pressure of $\frac{175}{b}ar$ at $90C.$ It flows through a process line in which the velocity should be no greater than $10\frac{m}{s}.$ What flow rate $($ kmo$\frac{l}{m}in)$ of the mixture can be handled by a $2-cm$ internal diameter pipe?

$*5\mathrm{.}102.$ A system has been devised to store acetonitrile safely at high pressures and temperatures. The acetonitrile is contained in a $0\mathrm{.}2-f{t}^3$ tank maintained at $4500$ psia and $550F.$ This tank is placed inside
