The Roof Of A House Consists Of A 22 Cm Thick Concrete Slab

The convection heat transfer coefficients on the inner and outer surfaces of the roof are 5 and 12 w m2k respectively.

The roof of a house consists of a 22 cm thick concrete slab.

On a clear winter night the ambient air is reported to be at 10 c while the night sky temperature is 100 k. The rest of the slab is 4 or 6 inches thick. The ambient air is reported to be at 10 c while the night. The roof of a house consists of 15 cm thick concrete slab k 2 w mk that is 15 m wide and 20 m long.

A 4 or 6 inch layer of gravel lies beneath the slab. Live load 40 psf figure 1. Slabs s1 and s2 to be designed. The inner surface of the roof is maintained at 15 c.

The convection heat transfer coefficients on the inner and outer surfaces of the roof are 5 and 12 w m2 c respectively. Design the roof slab beam and column of house given in figure 1. 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. On a clear winter night the ambient air is reported to be at 10 c while the night sky temperature is 100 k.
