A flat plate solar collector is installed flat-flush on the surface of a roof that is inclined 30° from the vertical normal and facing south in order to maximize its performance. The solar collector is a 2.5 m × 2.0 m rectangle and is placed at a distance of 1.5 m from one edge of the roof, as shown in the figure. If the cover

plate of the solar collector is at 25°C when ambient air at 15°C is flowing parallel to it from the direction of the uncovered leading section of the roof and with a velocity of 2 m/s, estimate the rate of heat loss from the solar collector panel.
