Solar radiation is incident on two flat-plate collectors at a rate of 900 W/m². Both collectors have a surface area of 30 m². The single-glazing collector supplies hot water to a facility at a rate of 8 L/min, whereas the double-glazing collector supplies hot water at a rate of 10 L/min. Cold water enters the single-glazing collector at 25 °C and the double-glazing collector at 45 °C. If the efficiency of both collectors is considered as 75%, determine the temperature of hot water provided by each collector Note: The specific heat of the water can be taken as 4.18 kJ/kg°C.
