Determine the mimimum furnace output for a 2100 sq feet modern house using the formula B=31a
not much data to use, so it should be easy. Hmmm they give you "a" and a formula for B
How hard is it to plug a into the formula?
B = 31*2100
To determine the minimum furnace output for a 2100 square feet modern house using the formula B = 31a, you need to know the value of 'a' which represents the heated area of the house.
1. Start by measuring the heated area of the house. This can be done by measuring the square footage of each heated room separately and adding them together, or by simply measuring the entire floor area of the house if it is uniformly heated.
2. Once you have the value of 'a', substitute it into the formula B = 31a.
For example, if the heated area of the house is 1500 square feet, you would calculate:
B = 31 * 1500
B = 46500
So, the minimum furnace output for a 2100 square feet modern house with a heated area of 1500 square feet would be 46,500 BTU (British Thermal Units).
