The relation between water evaporated (W kg), coal consumption (C kg) and

The relation between water evaporated (W kg), coal consumption (C kg) and kWh generated per 8-hour shift for a steam generating station is as follows: W = 13500+ 7.5 kWh....(i) C = 5000+ 2.9 kWh....(ii) (i) To what limiting value does the water evaporating per kg of coal consumed approach as the station output increases? (ii) How much coal per hour would be required to keep the station running on no load?
