rate of heat loss for the following data.

Additional data: Ta = 350 C, ha = 1000
W/m2 ·K, hb = 20 W/m2 ·K, Tb = 20 C, L = 100
m.

2. Find the surface temperature, surface heat flux, and
linear heat generation rate of an electric resistor. The resistor is in the
form of a solid cylinder of diameter 0.2 in and k = 50 Btu/h·ft·F. Heat is
produced uniformly in the cylinder so that q___ = 5E7
Btu/h·ft3. Assume the center temperature is maintained at 300 F.
