A solar park in Spain consists of 400 parabolic mirrors. Each parabolic mirror has an area of 14×6 m2 focused onto a large metal cylinder containing 52 m3 water. The energy of water heated by ΔT [K] increases by W = cm∆T, where c = 4.18 [J/(g*K)]. Give an estimate in [minutes] of how fast the water will be heated from 15oC to 60oC, assuming the normal solar irradiance and albedo (1380 W/m2 and 0.30, respectively).
