A square footing is supporting a single interior column with a dimension of 12 in × 12 in. The column carries axial loads as follows: 100 kip dead load and 80 kip live load. Use normal-weight concrete with fc ′ = 3 ksi, fy = 60 ksi, and qa = 5 ksf. The distance from the bottom of the footing to final grade is 5 ft. The height of the footing is 36 in and the concrete cover is 3.5 in. Unit weight of the soil is 100 pcf and unit weight of concrete is 150 pcf. a) Determine the dimension of the footing (in 1.0-ft increment) and check if the depth is adequate. b) Design the flexural reinforcement of the footing. c) Design the dowel reinforcement.

Steam in a heating system flows through tubes whose outer radius is 2.5 cm and whose walls are maintained at a temperature of 180 °c . circular aluminum alloy 2024-t6 fins ( k= 186 wm. k) of outer radius 3 cm and constant thickness 1 mm are attached to the tube. the space between the fins is 3 mm and thus there are 250 fins per meter of tube length. heat is transferred to the surrounding air at too-25 °c, with a heat transfer coefficient of 40 w/m2. k. manufacturer a claims that this system is rated at 3.5 kw per meter of tube length. if the fins are an integral part of the steam tube, find the heat transfer rate in kw for a 1-m length of tube. is manufacturer a's claim valid? compare the heat transfer rate from 1 meter of tube length if there are no fins.
