TopicNetwork Flows

1 The network represents a system of pipes.
The number on each arc represents the upper capacity for each pipe in \(\mathrm { cm } ^ { 3 } \mathrm {~s} ^ { - 1 }\)

The maximum flow through the system is \(M \mathrm {~cm} ^ { 3 } \mathrm {~s} ^ { - 1 }\)
What does the value of the cut imply about \(M\) ? Circle your answer.
\(M < 60 \quad M \leq 60 \quad M \geq 60 \quad M > 60\)
