$100k\frac{g}{s}$ of ethylene are being compressed from $1$atm and $25C$ to $40$atm and $25C.$ Calculate:

a$.$ The specific volume in $\frac{L}{K}g$ at the entrance $(1$atm $)$ and exit $(40$atm of the compressor.

b$.$ The volumetric flow rate in $\frac{L}{s}$ at the entrance $(1$atm$)$ and exit $(40$atm $)$ of the compressor.

Use the generalized compressibility chart for calculating gas properties of non$-$ideal gases.

Additional data: $P_c=50\mathrm{.}5$atm,$T_c=283\mathrm{.}1K,=0\mathrm{.}087,MW=28\mathrm{.}05\frac{g}{m}ol$
