The upper surface of a flat plate absorbs a solar radiation while the upper surface is exposed to a convection environment under air flow at 18.8°c with the convection heat transfer coefficient of 18.9 w/ moc. The plate, 5 cm in thickness, has the thermal conductivity of 0.8 w/mºc. The bottom of the plate is maintained at 23.8"c, if the temperature of the upper surface of the plate is measured to bo 31.4°C, determine the not absorption rate of the solar radiation at the upper surface in W/m2). (The tolerance of your answer is 2%) Net absorption of solar radiation Convection I Conduction T Answer: Check
