Consider 1 m long section of two long parallel cylinders. They have 20 cm diameter and are located 30 cm apart from each other as shown in the figure. Both cylinders are black and are maintained at temperatures of 425 K and 275 K. The surrounding can be treated as a black body at 300 K.
What will be the rate of radiation heat transfer (in W) between the hot cylinder and the surroundings? (Answer up to the nearest integer)
    Correct answer is '705'. Can you explain this answer?

    The view factor between the hot cylinder and the surroundings is,
    F13 = 1 – F12 = 1 – 0.193 = 0.807 (Summation rule)
    The rate of radiation heat transfer between the hot cylinder and the surroundings per meter length of the cylinder is,
    A1 = π DL = π X 0.20 X 10 = 0.6283 m2
    = 0.6283 x 0.807 x 5.67 x 10–8 x (4254 – 3004)
    = 705 W
