Calculate the top heat-loss coefficient for a solar collector with a single glass cover having the following specifications (neglect edge effects), also calculate the ambient air temperature:
Overall heat-loss coefficient 3.46 W/(m2.K)
Convection heat-transfer coefficient (hc,p-c) 2.65 W/(m2.K)
Spacing between the plate and the cover 2.5 cm
Plate emissivity 0.2
Glass emissivity 0.88
Back insulation thickness 5 cm
Conductivity of back insulation material 0.045 W/(m.K)
Mean plate temperature 373 K
Temperature of cover 298 K
Collector tilt 45o
Wind heat transfer coefficient 10 W/(m2.K)
