A steel tube with 5 cm ID, 7.6 cm OD and k=15W/m °C is covered withan insulative covering of thickness 2 cm and k 0.2 W/m °C. A hot gasat 330° C with h = 400 W/m2oC flows inside the tube. The outer surfaceof the insulation is exposed to cooler air at 30°C with h = 60 W/m2oC.Calculate the heat loss from the tube to the air for 10 m of the tube andthe temperature drops resulting from the thermal resistances of thehot gas flow, the steel tube, the insulation layer and the outside air.

A 100 mm concrete wall is to be used to make a cold storage. The floor and ceiling is to use the same material. The room is supposed to have height of 5 m, length of 7 m and a width of 6 m. The ambient temperature is 36 degrees and the room has to be cooled at 3 degrees. The cold storage is to be used to cool 1600 kg of milk. Conduct the cooling load calculation for the room and determine the cooling capacity of the cooling equipment required for this room. Subject- Civil Engineering Only correct answer

Solve for what is being required. 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.
