Problema Solution
The formaula B=34a is used in new England to estimate the minimum furnace output, BI in BTUS for modern house with the amount of square feet flooring
(a) determine the minimum furnace output for 2200ft modern house
solve formula for a
Answer provided by our tutors
Since B = 34a and a = 2200 ft^2 we can calculate the minimum furnace output:
B = 34 * 2200 = 74,899 BTU
from B = 34a we can derive the formula for 'a' that is
a = B / 34.
