The surface area of concentrator type solar heater is 5m^2 It can reflect 80% of solar radiation incident - Science - Sources of Energy

Question

The surface area of concentrator type solar heater is 5m^2 It can
reflect 80% of solar radiation incident while it absorbs the rest
Calculate energy concentrated by heaters as it focuses in 2 hours
if solar energy was delivered to it at the rate 0 4 kJ+m/2s

Dear Student

Energy concentrated = Reflecting percentage of energy × Surface area× Time × Rate of solar energy delivered ⇒ 80100 × 5 ×(2 × 60 × 60) × 0
4×103 ⇒ 11520 × 103J⇒11
52 × 106 J ⇒ 11 52 MJ
