- Estimate the 1998 total installed cost for the baghouse of Problem 6.4, assuming it is mild steel and is insulated, Assume the baghouse uses polypropylene bsgs with loop tops.A 162-foot roll of #10 wire is used when installing a residential airconditioningunit. Lengths of 17 feet and 18 feet are cut from the roll. Howmany feet are left?A magnetic strip fits around the grill of this air-conditioning unit. How longmust the strip be to completely fit around the grill?
- Answer ONLY items 5-8. Room dimensions are: LxWxH = 8.50 m, 5.0 m, 3m. Originally, the room had linoleum flooring with an absorption coefficient of 0.03. Two opposite walls were cladded with unglazed bricks with an absorption coefficient of 0.02, the one having the entrance gypsum door (2.1 m X 0.80 m) with 0.05 abs.co.; the other two were just bare concrete with sliding glass window openings of 1.80m x 1.20 m each; the bare concrete with an abs.co. Of 0.31 and the window glass with 0.18, the ceiling, too , had bare concrete as its finish at 500 Hz. The client would like to renovate the space into an acoustical studio room and would like to change the ceiling and the flooring. The ceiling will have a vinyl faced fiberglass panel with an abs.co. of 0.71, and the floor will have mineral fiber tiles with an abs.co. Of 0.66, all at 500 Hz.Civil engineering--Q17 - A metallic column is covered through 1 in. Thick (25.4 mm) spray implemented cementitious cloth.
