Heat loss due to radiation for a pipe is 80.0 kW. The pipe is 100.0 m long and its outer radius is 10.0 cm. The surface emissivity of the pipe is 0.70. Find the temperature of the pipe.
Calculate heat loss per meter length due to radiation of a metal pipe with an emissivity of 0.930. The temperature of the outer surface of the pipe is 311 K. The outer diameter of the pipe is 15.24 cm.
A 100-meter-long pipe is at a temperature of . Find the heat loss due from the pipe due to radiation if the pipe’s outer diameter is 10 cm. The surface emissivity of the pipe is 0.7.
