Question

8. A spherical container having outer diameter as 500 mm is insulated by 100 mm thick layer of ma (Thermal Conductivity, K = 0.03 (1+0.006t) watt/m C). If the surface temperature of sphere is -200 C temperature of outer surface is 30C. Determine the heat flow,​

Answer 1

Answer:

The rate of heat transferQt (energy per unit time) is proportional to the temperature difference T2 − T1 and the contact area A and inversely proportional to the distance d between the objects: Qt=kA(T2−T1)d Q t = kA ( T 2 − T 1 ) d .
