12. Imagine a solar collector for hot tap water in a hot climate. De outdoor temperature is 22 degree Celsius. De tank of the solar collector is placed outside, and the cold water temperature to the collector is 20 degree Celsius. De water flow rate through the collector is 45 liter/hour. De collector is 2 [m2] and the average solar radiation in the time period considered is 1000 [W/m2]. What is the temperature of the hot water to the tank? The efficiency of the collector can be assumed to be 0.7 (we neglect the dependency to the water temperature) (multiple choice, one answer) 34 [OC] O 47 [OC] 54 [OC] 67 [OC]

12. Imagine a solar collector for hot tap water in a hot climate. De outdoor temperature is 22 degree Celsius.
De tank of the solar collector is placed outside, and the cold water temperature to the collector is 20 degree
Celsius. De water flow rate through the collector is 45 liter/hour. De collector is 2 [m2] and the average solar
radiation in the time period considered is 1000 [W/m2]. What is the temperature of the hot water to the tank?
The efficiency of the collector can be assumed to be 0.7 (we neglect the dependency to the water
temperature) (multiple choice, one answer)
