An experiment is performed to measure the heat transfer from a flat aluminium plate, which is being cooled on its top surface by convection. The plate has been instrumented with a pair of thermocouples. The mean temperature at the top of the plate is 360 K and the mean temperature at the bottom of the plate is 307 K. The aluminium has a thermal conductivity of 170 W/m/K. The plate has a uniform thickness of 16 mm. Calculate the heat flux per unit area, in units of kW/m². Provide your answer to three significant figures. You may assume the temperature over the top and bottom surfaces of the plate are uniform.
