A pipeline of \(300 \mathrm{~m}\) length supplies liquid chlorine from a regulated 20 barg source to a process through a horizontal, new commercial steel pipe of actual inside diameter of \(2 \mathrm{~cm}\). The ambient pressure is \(1 \mathrm{~atm}\) and everything is at a temperature of \(30^{\circ} \mathrm{C}\).

a. If the pipe breaks off at the end of the \(300 \mathrm{~m}\) length, estimate the flow in \(\mathrm{kg} / \mathrm{s}\). Neglect entrance and exit effects and assume that the frictional loss is entirely due to the pipe length.

b. If the pipe breaks off at the regulated source, estimate the flow in \(\mathrm{kg} / \mathrm{s}\).

For chlorine, the following properties are available:

Density: \(1380 \mathrm{~kg} / \mathrm{m}^{3}\)

Viscosity: \(0.328 \times 10^{-3} \mathrm{~Pa}-\mathrm{s}\)
