(12 pts): A flat-plate solar panel is placed in free stream air at 10 °� of 1 m long and 1 m wide. Air is flowing along the length of the plate. The free stream velocity is 2 m/s. The solar panel is generating heat at a constant heat flux of 3 W/m2 . Assuming all surfaces of the solar panel are insulated, except the top surface. Assume steady-state. The air properties at 10 °� are listed as follows: Kinematic viscosity � = 5.21 × 10%- m2 /s, conductivity � = 36.4 × 10%.W/mK, Prandtl number �� = 0.687, and density � = 1.1 kg/m3 (a) (2 pt) Calculate the total cooling rate of the solar panel. (b) (2 pt) Sketch how the heat transfer coefficient h changes with the length of the plate. (c) (4 pt) Calculate the average heat transfer coefficient h<. (d) (4 pt) Suppose the solar panel needs to be bolted to the top of the roof. Estimate the force that is exerted on the bolt.
