Question: on a still clear night the sky behaves as a...

Question details

On a still, clear night, the sky behaves as a blackbody with an equivalent temperature of 250K. At what air temperature will a strawberry field cool to 0°C and freeze if the heat transfer coefficient** between the plants and the air (with a light breeze) is 6Y and the plants have an emissivity of 0.9? m- K a) 14°C d) 0°c b) e) 7°C c) 3°C -3°C *Note that the combined heat transfer coefficient is defined as, rad+conv combined T. T. surf 00 which is a convective heat transfer coefficient, modified to include radiation heat transfer to or from the surrounding fluid.
