There are two aspects of fluid behavior that need explanation:

the spreading of fluids over ground, and the rates of flow of bodies of water.

Spreading of fluids over the ground is divided into two cate gories, water and oil, as shown in the following table.

The Time is the time in phases for full coverage, and Area is the number of hexes covered.

Spreading Times For Fluids Time Area Time Area Size Water Oil Water Oil Size Water Oil Water Oil 1 cup 1 1 .25 .25 5 gal.

4 8 18 15 1 qt.

1 1 1 1 10 gal.

7 13 34 29 1 gal.

2 3 4 3 20 gal.

12 22 64 56 2 gal.

3 4 8 6 50 gal.

26 50 150 120 On sandy soil halve the area covered.

Although the time for spreading may seem a little long, 75% of the area is covered in half the listed time.

The speeds of various types of flows are given in the following table.

Water Flow Rates Water Flow Speed MPH/HPP Water Flow Speed MPH/HPP delta or marsh river 1 I 1.5 flash flood 40 I 60 plains river 3/4.5 ocean currents 41 6 mountain river 81 12 riptides 61 9 whitewater 161 24
