Calculate the overall heat loss coefficient, Physics

Calculate the overall heat-loss coefficient for a solar collector with a single glass cover having the following specifications (neglect edge effects):

Spacing between the plate and the cover                   5 cm

Plate emittance                                                            0.2

Glass emittance                                                           0.88         

Ambient air temperature                                             283 K

Back insulation thickness                                            3 cm

Conductivity of back insulation material                    0.04 W/(m.K)

Mean plate temperature                                              340 K

Collector tilts                                                              45°

Wind - heat transfer coefficient                                 10 W/(m2.K)
