The turbines in a hydroelectric plant are fed by water falling from a 40 m height. Assuming 90% efficiency for conversion of potential to electrical energy, and 6% loss of the resulting power in transmission, what is the mass flow rate of water (in kg/min) required to power a 150 W light bulb? [Write your answer to the nearest whole number]
