If it is desired to melt aluminium with solid state specific heat 0.9 kJ/kg K, latent heat 390 kJ/kg, atomic weight 27, density in molten state 2400 kg/m³ and final temperature 700°C, find out how much metal can be melted per hour with the above kW rating. Other data are as in the above example. Also, find the mass of aluminium that the above furnace will hold. The melting point of aluminium is 660°C .
