WebAssuming one –dimensional heat transfer, determine the rate of heat transfer. Fig. 10-4 Schematic for example 10-1. Solution: The rate of heat transfer through this composite … WebCooling by a transfer of heat by radiation from the plants to the cooler night sky was inhibited. This was possible only in the "open" experiments of 1931-1934 in Petersham (Pkaes 5 and 6). Under the Môller house in the 1930 experiments (Plates 3, 4 and 5) the glass roof would prevent radia- tional cooling of the plants outside the water-filter.
