We are testing a 2 cm thick insulating material. The density, thermal conductivity, and heat capacity of the insulating material are 255 kg/m°, 0.07 W/m. K, and 1300 J/kg. K, respectively. If our experiments take 10 min, is it possible to assume pseudo-steady-state behavior? For the pseudo-steady-state approximation to be valid, we must satisfy, atch > 1 L2 ch

S A 10-m-long section of an 8 cm (r=4 cm) of external diameter horizontal steam water pipe passes through a large room whose temperature is To =15°C. The pipe is insulated with an insulating material of conductivity k=0.01 W/m-°C and 1 cm thick. If the inner surface temperature of the pipe is 95 °C (at r2) and the pipe is exposed to a cross wind of 6.0 m/s, determine the rate of heat loss from the pipe (neglect radiation). Thermal...
