A furnace of 250 MW rating is used to melt and raise the temperature of
aluminium from 25 oC to 900 oC. Aluminium has a solid-state specific heat, latent
heat, and liquid-state specific heat of 0.9 kJ/kg-K, 390 kJ/kg, and 1.108 kJ/kg-K,
respectively, and the furnace has 70% efficiency. The melting point of aluminium
is 660 oC. The amount of aluminium that can be processed per hour is
________ kg (rounded off to 1 decimal place).
