The total area of the Hubble telescope exposed to the sun is 70 000 m ² . The rate of solar energy incident on the telescope is 120 W m ^-2 . If a channel covering the entire exposed surface contains water and the temperature of the water must rise by at least 10 ^o C in order to keep the telescope cool, at what approximate rate must the water be made to flow assuming that energy transfer is instantaneous?

Specific heat capacity of water = 4.2 J g ^-1 oC ^-1

Density of water = 1000 kg m ^-3
