A pipeline of 300m 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 cm. The ambient pressure is 1 arm and everything is at a temperature of 30oC. If the pipe breaks o at the end of the 300m length, estimate the ow in kg=s. neglect entrance and exit effects and assume that he frictional loss is entirely due to the pipe length.
