What temperature is achieved in solar cooker/solar water heater ?
Answer» Solution :TYPICALLY solar cooker is designed to achieve `65^(@)C(150^(@)F)` temperature. The temperature of WATER in the solar water heater is determined by the combination of collector area and the tank CAPACITY. Typically it would be `50-60^(@)C`, which is much hotter than the BATHING water temperature (around `40^(@)C`).
