4. Consider a steam pipe of length L = 15 m, inner radius r₁ = 8 cm, outer radius r2 = 10 cm, and thermal conductivity k = 20 W/m°C. The inner and outer surfaces of the pipe are maintained at average temperatures T₁ = 120°C and T₂ = 40°C, respectively. Under steady conditions, determine the rate of heat loss from the steam through the pipe.

conductivity k = 20 W/m°C. The inner and outer surfaces of the pipe are maintained at average
temperatures T₁ = 120°C and T₂ = 40°C, respectively. Under steady conditions, determine the rate of heat
loss from the steam through the pipe.
