Fluid Energy

Severe Tropical Cyclone Zelia is predicted to bring “sustained winds near the centre of 175kph and wind gusts up to 250kph” Let’s call it 200 Km/hour.

Meanwhile, back at the ranch, we had gusts up to 123 and 110 last Friday and Monday. Let’s call that 100 Km/hr.

Now 200 is two times 100, and dance the energy in a moving fluid is proportional to the cube of its velocity, we can say that coastal areas in the north of Western Australia will experience energies eight times what we experienced last week.

Remember that cubed factor, and think about it before you try to cross that flooded creek.
