$8.$ Liquid chlorine is supplied to a process from a regulated pressure source at $20$ barg through $300$ m of horizontal new commercial steel pipe of actual inside diameter of $0\mathrm{.}02$ m$.$

The ambient pressure is $1$ atm and the ambient temperature is $30$oC$.$

a$.$ If the pipe breaks off at the regulated source, estimate the flow rate through the leak, in kg$/$s$.$

b$.$ If the pipe breaks off at the end of the $300-$m length, estimate the flow in kg$/$s$.$

For chlorine, the following properties are available at these conditions:

$$ Density: $1380$ kg$/$m$3$

$$ Viscosity: $0\mathrm{.}328\backslash$times $103$ Pa$-$s
