The Roof Of A House Consists Of A 3 Cm Thick Concrete Slab

The roof of a house consists of a 22 cm thick concrete slab k 2 w m k that is 15 m wide and 20m long the emissivity of the outer surface of the roof is 0 9 and the convection heat transfer coefficient on that surface is estimated to be 15 w m 2 k the inner surface of the roof is maintained at 15 c.

The roof of a house consists of a 3 cm thick concrete slab.

The convection heat transfer coefficients on the inner and outer surfaces of the roof are 5 and l w m 2 k respectively. On a clear winter night the ambient air is reported to be at 10 c while the night sky temperature is 100 k. 1 conduction sheet 3 1 the roof of a house consists of a 3 cm thick concrete slab k 2 w m c that is 15 m wide and 20 m long. On a clear winter night the ambient air is reported to be at 10 c while the night sky temperature is 100 k.

On a clear winter night the ambient air is reported to be at 10 c while the night sky temperature is 100 k. Concrete compressive strength fc 3 ksi. Slabs s1 and s2 to be designed. The convection heat transfer coefficients on the inside and outside surfaces of the roof are 5 and 12 w m k respectively.

The roof of a house consists of a 15 cm thick concrete slab k 2 w m k that is 15 m wide and 20 m long. On a clear winter night the ambient air is reported to be at 10 c while the night sky temperature is 100 k. The roof of a house consists of a 3 cm thick concrete slab k 2 w m κ that is 15 m wide and 20 m long. Design the roof slab beam and column of house given in figure 1.

2 thick brick tile. The ambient air is reported to be at 10 c while the night. The convection heat transfer coefficients on the inner and outer surfaces of the roof are 5 and 12 w m2 c. Steel yield strength fy 40 ksi.

The rest of the slab is 4 or 6 inches thick. Around the edge of the slab the concrete forms a beam that is perhaps 2 feet deep. The roof of a house consists of a 15 cm thick concrete slab k 2 w m c that is 15 m wide and 20 m long. On a clear winter night.

The inner surface of the roof is maintained at 15 c. The roof of a house consists of a 22 cm thick concrete slab k 2 w m k that is 15 m wide and 20 m long the emissivity of the outer surface of the 1 roof is 0 9 and the convection heat transfer coefficient on that surface is estimated to be 15 w m 2 k. A 4 millimeter sheet of plastic lies between the concrete and the gravel to keep moisture out. The roof of a house consist of 15 cm thick concrete slab k 2 0 wm k that is 15 m wide and 20 m long.

Live load 40 psf figure 1. A 4 or 6 inch layer of gravel lies beneath the slab. The convection heat transfer coefficients on the inner and outer surfaces of the roof are 5 and 12 w m2 c respectively.
