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

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.

The roof of a house consists of a 3 cm thick concrete slab. 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. 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 m2 k. The roof of a house consists of a 22 cm thick concrete slab k 2 w m k that is 16 8 m wide and 20 m long. The average ambient air and the night sky temperatures for the entire night are predicted to be 6 c and 260 k respectively.

The inner surface of the roof is maintained at 15 c. Live load 40 psf figure 1. 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 the convection heat transfer coefficients on the inner and outersurfaces of the roof are 5 and 12 w m 2 k respectively. 2 thick brick tile.

The convection heat transfer coefficient of the inner surface of the roof is 5 w m2k. The convection heat transfer coefficients on the inner and outer surfaces of the roof are 5 and 12 w m2 c respectively. 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. The roof of a house consists of a 15 cm thick concrete slab k 2 w m c 15 m wide and 20 m long.

Slabs s1 and s2 to be designed. Concrete compressive strength fc 3 ksi. One evening at 6 pm the slab is observed to be at a uniform temperature of 18 c. On a clear winter night the ambient air is reported to be at 10 c while the night sky temperature is 100 k.

The temperature of the air near surface of the roof is 10 o c convection and the temperature of the night sky for radiation calculations is 100 k. The roof of a house consists of a 15 cm thick concrete slab k 1 4 w m k and α 0 69 10 6 m 2 s that is 18 m wide and 32 m long. 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. The inner surface of the roof is maintained at 15 c.

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 200 k. Design the roof slab beam and column of house given in figure 1.
