Highly social, Prairie Dogs live in large colonies called âtownsâ and in collections of families that can span hundreds of acres. A Prairie Dog town may contain 15 to 26 family groups, made up of a series of burrows with mounded entrances. Mother Prairie Dogs provide most of the care for the young.
BTU, or British thermal unit, is the industry-standard used to measure the heating efficiency of furnaces. In addition to BTU ratings, furnace manufacturers might include a Manual J Load rating and a percentage of energy efficiency.
A BTU is a measure of energy. There is no way to compare them. Possible meaning: 1 ton of cooling is often used to describe 12,000 BTU peâ¦r hour, so 36,000 BTU/h is equal to 3 tons of cooling. Amir Karimipour.
