Solved: A solar cooker consists of a curved reflecting
Chapter , Problem 67(choose chapter or problem)
A solar cooker consists of a curved reflecting mirror that focuses sunlight onto the object to be heated (Fig. P11.67). The solar power per unit area reaching the Earth at the location of a 0.50-m-diameter solar cooker is 600 W/m2. Assuming 50% of the incident energy is converted to thermal energy, how long would it take to boil away 1.0 L of water initially at 20C? (Neglect the specific heat of the container.)
