Body's surface tissue as layer of thickness X1=5 cm which has a thermal conductivity K1= o.59 J/m. s.C .

This is surrounded by a layer of tissues fat of thickness X2=2 cm

with K2=0.21 J/m. s.0C .The body's interior is at temperature T1=37C

and the skin temperature is T2=33.5C

.What is the heat loss per unit area?

What is the conversion factor between kg/m^3 and g/m^3. express your experimental values for the densities in kg/m^3.

The graph describes the motion of an object. the object moves with from a to b. it from b to c. it moves with from c to d.

Asheet of steel 1.5 mm thick has nitrogen atmospheres on both sides at 1200oc and is permitted to achieve a steady-state diffusion condition. the diffusion coefficient for nitrogen in steel at this temperature is 6 x 10- 11 m2 /s, and the diffusion flux is found to be 1.2 x 10-7 kg/m2 -s. also, it is known that the concentration of nitrogen in the steel at the high-pressure surface is 4 kg/m3 . how far into the sheet from this high-pressure side will the concentration be 2.0 kg/m3 ? assume a linear concentration profile.
