When the volcano erupted in 2011 issued a hot cloud reaches 300km/hour speed, distancefrom the top of the mountain farm fields as far as 10 miles, the fields owned by residentspertanan around 1000 hectares of mountain slopes pants. If the hot clouds only up tokilometers to 20, what percentage of the charred fields due to hot clouds and how many hours of hot clouds can scorch the field? (If pyroclastic flows in all directions and fields in the form of a square)
Given:
Hot cloud velocity = 300 km / h
Field distance from the top of the mountain is 10 km
Area of field = 10,000 ha = 100.000.000 m2
Hot clouds up to 20 km
Question:
What percentage of the charred fields due to hot clouds?
how many hours can be scorching hot cloud fields?
Answer:
Width fields:
√ 100 million = 10,000 m
The amount of the forfeited lands:
20-10 = 10km
Percent of land forfeited: (10/10.000) * 100% = 0.01%
Heat can scorch time cloud fields:
Time = 200/300 = 2 / 3 = 0.67 hours = 40 minutes = 2400 seconds
