Unsteady mass transfer from a 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.

WebIn most cases (exceptions: free convection due to density differences and radiation heat transfer), the heat flow rate is proportional to the temperature difference. In other words, from B to A we have ̇∝ − . Note this means that heat transfer, unlike fluid mechanics, is often a linear problem.
