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)
