Two parallel plates of infinite extent perpendicular to the page are situated relative to each other as shown in the figure. The upper plate is at 300°C and the lower plate is at 100°C. Determine the net rate of radiation heat transfer from the upper and lower plate assuming the environment is at a temperature below 100°C. Assume that both the lower surface of the upper plate and the upper surface of the lower plate are black.
GIVEN
• Two parallel plates of infinite extent perpendicular to the page.
• Upper plate temperature (T2) = 3000C
• Lower plate temperature (T1)= 1000C
• Length of the plates L1 = L2 = 2 m
• Distance between the plates (R) = 1 m
FIND
(a) Net rate of radiation heat transfer from upper and lower plate.
ASSUMPTIONS
• Lower surface of upper plate and upper surface of lower plate are black.
