AFUE of 90 means?
Furnaces (and boilers) are rated by the annual fuel utilization efficiency (AFUE) ratio, which is the percent of heat produced for fuel consumed. A furnace with an AFUE of 90 will turn 90% of its fuel into useable heat. Any furnace with an efficiency of 90% or higher is considered high-efficiency.

What has the biggest impact on the design of a concert hall during SD?

Different types of performances require different spaces. The needs of a concert hall are different than both a theater for drama and one for movies. Desirable reverberation time, stage size, and audience arrangement and sight lines all vary with the type of theater.
What is the most dimensionally stable lumber
Rift sawn
what is a curtain drain
A trench in the earth that is filled with gravel and topped with a perforated pipe and drain cover. It is used to collect stormwater like a gutter system collects water. The water collects in the perforated pipe and runs to daylight.
Unforeseen site conditions dictate dimensional changes for the footing of a column. It is found that the footing width cannot be wider than 7 feet.
Knowing that the allowable bearing capacity of the soil is 4.5 kip / sq ft, what should the length of footing be, if the column above weighs 100,000 pounds and has to bear an assigned live load of 160,000 pounds? N.B. 1kip = 1,000 pounds = 1,000 lb
First, we label L = the length of footing that needs to be determined. The allowable bearing capacity for our column can be defined as follows:
p [kip/sq ft] = N [pounds or kips] / A [sq ft]
- 5 kip/sq ft = (100,000 lb + 160,000 lb ) / 7 ft x L
- 5 kip/sq ft x 7 ft x L = 100 kip + 160 kip
L = 260 / 31.5
L= 8.25 ft = 8’-3”
