Q: A 2.5-cm-OD hot steam line at 100°C runs parallel to a 5.0 cm OD cold water line at 15°C. The pipes are 5 cm center to center and deeply buried in concrete with a thermal conductivity of 0.87 W/(m K). What is the heat transfer per meter of pipe between the two pipes?
GIVEN
A hot steam line runs parallel to a cold water line buried in concrete
Hot pipe outside diameter (Dh) = 2.5 cm = 0.025 m
Hot pipe temperature (Th) = 100°C
Cold pipe outside diameter (Dc) = 5.0 cm = 0.05 m
Cold pipe temperature (Tc) = 15°C
Center to center distance between pipes (l) = 5 cm = 0.05 m
Thermal conductivity of concrete (k) = 0.87 W/(m K)
ASSUMPTIONS
Two dimensional heat transfer between the pipes
Steady state conditions
Uniform thermalconductivity
