Wetlands

All of the swamps in the wetlands are empty! The wetlands consist of 10 swamps as shown in the map.

The numbers represent the capacities in megalitres (ML) of the swamps. The arrows show the direction that water can flow along a channel connecting two swamps.

One hundred ML is being pumped into the leftmost swamp. Once a swamp is filled, any excess flows to the next swamps, dividing equally when there is more than one channel.

Question:

How many ML of water will flow into the rightmost swamp?
